Use SHIFT-PgUp and SHIFT-PgDn to scroll back and forward.
Aarons original code was enhanced to have a separate scrollbuffer
for every virtual terminal and to preserve the screen contents
when switching screen sizes.
The scrollbuffer size is currently fixed at 8 pages but this
will be made configurable through the use of scon(1) in the
near future.

two sign-bugs.
Apply the hardpps() phase with the right sign with a simply
scaling by integration interval. (This may be too stiff at
long integration intervals, see below).
Allow pps_shiftmax to be reduced again.
Before this, the phase lock in hardpps() were broken, but due to
two bugs mostly cancelling out, it would end up basically working
with a large stochastic component. Now it behaves as one would
expect: smooth and quiet.
It seems that pps_shiftmax above 7..9 somewhere makes the phaselock
too weak to hold onto random walk phase errors from a HP-105 OCXO,
which basically means that it is too weak for real-life use with
such integration times. This is yet to be resolved.

swap_pager.c and related commits.
Essentially swap_pager.c is backed out to before the changes, but
swapdev_vp is converted into a real vnode with just VOP_STRATEGY().
It no longer abuses specfs vnops and no longer needs a dev_t and
/dev/drum (or /dev/swapdev) for the intermediate layer.
This essentially restores the vnode interface as the interface to the
bottom of the swap pager, and vm_swap.c provides a clean vnode interface.
This will need to be revisited when we swap to files (vnodes) - which
is the other reason for keeping the vnode interface between the swap pager
and the swap devices.

USB ethernet chip. Adapters that use this chip include the LinkSys
USB100TX. There are a few others, but I'm not certain of their
availability in the U.S. I used an ADMtek eval board for development.
Note that while the ADMtek chip is a 100Mbps device, you can't really
get 100Mbps speeds over USB. Regardless, this driver uses miibus to
allow speed and duplex mode selection as well as autonegotiation.
Building and kldloading the driver as a module is also supported.
Note that in order to make this driver work, I had to make what some
may consider an ugly hack to sys/dev/usb/usbdi.c. The usbd_transfer()
function will use tsleep() for synchronous transfers that don't complete
right away. This is a problem since there are times when we need to
do sync transfers from an interrupt context (i.e. when reading registers
from the MAC via the control endpoint), where tsleep() us a no-no.
My hack allows the driver to have the code poll for transfer completion
subject to the xfer->timeout timeout rather that calling tsleep().
This hack is controlled by a quirk entry and is only enabled for the
ADMtek device.
Now, I'm sure there are a few of you out there ready to jump on me
and suggest some other approach that doesn't involve a busy wait. The
only solution that might work is to handle the interrupts in a kernel
thread, where you may have something resembling a process context that
makes it okay to tsleep(). This is lovely, except we don't have any
mechanism like that now, and I'm not about to implement such a thing
myself since it's beyond the scope of driver development. (Translation:
I'll be damned if I know how to do it.) If FreeBSD ever aquires such
a mechanism, I'll be glad to revisit the driver to take advantage of
it. In the meantime, I settled for what I perceived to be the solution
that involved the least amount of code changes. In general, the hit
is pretty light.

(1) Accesses to the RTC index and data registers were not atomic enough.
Interrupts were not masked. This was only good enough until an

(2) Access to the block of time registers in inittodr() was not atomic

were not masked. This was only good enough until something (apm)
started calling inittodr() after boot time in FreeBSD-2.0.
The fix for (2) also makes the timecounter update more atomic, although
this is currently unimportant due to the low resolution of the RTC.

- In uhci_intr() check to see if sc->sc_bus.bdev is NULL, and if it is,
ack any pending interrupts and disable them, then return. It is possible
for interrupts to be delivered the moment a handler is set up at attach
time in uhci_pci.c, particularly when attempting to kldload the usb.ko
module after the system is already up. However the driver isn't ready
to field interrupts at that time and certain pointers in the softc
struct aren't initialized yet, and we invariably end up falling off
the end of one of them. The effect is that kldloading the usb module
will panic the system in uhci_intr(). This added sanity check stops
this from happening: I can now kldload the usb.ko module without any
problems and load/attach other USB drivers after it.
Of course the uhci driver has no detach method, but that's another
problem.
- In uhci_run(), set the UHCI_CMD_MAXP bit in the command register to
allow 64-byte packets to be used for full speed bandwidth reclamation.
Certain high speed devices (in this case the ADMtek USB ethernet
adapter) require this bit to be set, otherwise babble errors occur
at the end of large (between 1100 and 1500 byte) transfers. This
should not affect other devices, although supposedly it is less efficient
than the 32-byte setting. Unfortunately, this is a per-bus setting,
not a per-device setting, so we can't just enable it for certain
devices on the USB bus.

Add support, kinda, for megaheartz xjack nic cards. This support
works well for one machine per ethernet segment because it hard codes
the MAC address. The pccardd in -current doesn't have support to
