This make "_NEC" devices appear as "NEC" which is more corrent.
The reason is tha NEC originally screwed up on the byteorder in the
model string, so now that they have realized that they prefixed the '_'
so that not every ATA driver on the planet would call them "EN C" :)
reserving it at use time is more miserly, low memory (< 16MB)

isa_dma_init to ease merging to 5.

a hint as whether the car has crashed (which happens all too often).

errors for the attachment process for the floppy controller. This is
a band-aide because it doesn't try any of the fallback methods when
_FDE isn't long enough, but should be sufficient for people
experiencing the dreaded mutex not initialized panic.
problems:
1) Add locking for SMP, code provided by Alan Cox
2) While testing Alan's patches, I observed serious problems with
the jumbo buffer allocation code (machine crashed twice), so I gutted
it and rewrote the receive handler to use multiple chained descriptors.
Each RX descriptor gets a single 2K cluster, and the chip will fill in
as many as it needs to hold the complete packet.
User reports that this corrects the data corruption issues previously
observed and discussed on -current.
Note that this driver still needs to be hit with the busdma stick.
I intend to inflict said beating in the near future.

o Allow for up to 3 resource I/O ranges to be given for the floppy
controller, rather than just two that are allowed for now.
o Make sure that we can work with either a base address of 0x3f0 or 0x3f2.
o Create new inline functions to access the YE DATA's unique BDCR register.
o Update pccard attachment to add the fd device.
o Do some minor style(9) polishing.
# I'm guessing that the fdc pccard attachment broke some time ago, since

results in programming the chip with the correct frequency, which in turn
allows devices to negotiate up to the full 20MB/s.

The vge driver has been added to GENERIC for i386, pc98 and amd64,
but not to sparc or ia64 since I don't have the ability to test
it there. The vge(4) driver supports VLANs, checksum offload and
jumbo frames.
Also added the lge(4) and nge(4) drivers to GENERIC for i386 and
pc98 since I was in the neighborhood. There's no reason to leave them
out anymore.
holds sndstat_lock across a call to uiomove(), which is not legal
to do with a mutex because of the possibility that the data transfer
could sleep because of a page fault. It is not possible to just
unlock the mutex for the uiomove() call without introducing another
locking mechanism to prevent the body of sndstat_read() from being
re-entered. Converting sndstat_lock to an sx lock is the least
complicated change.
This is a candidate for RELENG_5.

we don't attach any devices. This was leaving stale device_t's

produced better results for a test program I had here, it didn't
substantially change the number of crashes that I saw. Both the old
code and the new code seemed to produce the same crashes from the usb
layer. Since the new code also solves a close() crash, go with it
until the underlying issues wrt devices going away can be addressed.
The reference counts are there to block detach until the sleepers in
read/write/ioctl have gotten out, not to prevent the open device from
going away. Restore the old behavior so that we have a chance to wake
up sleepers when the usb device goes away, so they can properly return
EIO back to the caller when this happens.
Otherwise, we have a guarnateed panic waiting to happen when a device
detaches with an active read channel.
This should be merged to 5 asap.
would turn off all fans when initializing a zone. However, the HP Omnibook
500 generates a notify saying the zone needs to be re-evaluated whenever
its fan is switched on or off. This produced an infinite loop. Also, note
that running _SCP can generate the same notify.
Since we need to make sure old fan references are turned off when getting
new ones, run acpi_tz_monitor() first. This will turn off any unneeded
fans. Then, check for new settings. After that, run acpi_tz_monitor()
again to turn on/off any fans referenced by the new settings.

around a problem in systems that don't correctly report the state (i.e.
the HP Omnibook 500 reports "on" for its fan always after it has been
turned on once).
I was unable to test this as the PAE kernel crashed with a "cannot copy

to RS232 bridges, such as the one found in the DeLorme Earthmate USB GPS
receiver (which is the only device currently supported by this driver).
While other USB to serial drivers in the tree rely heavily on ucom, this
one is self-contained. The reason for that is that ucom assumes that
the bridge uses bulk pipes for I/O, while the Cypress parts actually
register as human interface devices and use HID reports for configuration
and I/O.
The driver is not entirely complete: there is no support yet for flow
control, and output doesn't seem to work, though I don't know if that is
because of a bug in the code, or simply because the Earthmate is a read-
only device.
