callers. These ioctls attempted to enable and disable the ACPI
interpreter at runtime. In practice, it is not possible to boot with
ACPI and then disable it on many systems and trying to do so can cause
crashes, interrupt storms, etc. Binary compatibility with userland is
retained.

data packet is received from the mouse. In the case of many KVM's,
this avoids a bug in their mouse emulation that sends back incorrect
sync when you explicitly request a data packet from the mouse. Without
this change, you must force the driver into stock PS/2 mode or be flooded
with a never ending stream of "out of sync" messages on these KVMs.

The ISA probe uses an identify routine to probe all slot locations from
1 to 14 that do not conflict with other allocated resources. This required
making aic7770.c part of the driver core when compiled as a module.

Use aic_scb_timer_start() consistently to start the watchdog timer.
This removes a few places that verbatum copied the code in
aic_scb_timer_start().
During recovery processing, allow commands to still be queued to
the controller. The only requirement we have is that our recovery
command be queued first - something the code already guaranteed.
The only other change required to make this work is to prevent
timers from being started for these newly queued commands.

This was tested with a Netgear WG311v2 802.11b/g PCI card. Things
that were fixed:
- This chip has two memory mapped regions, one at PCIR_BAR(0) and the
other at PCIR_BAR(1). This is a little different from the other
chips I've seen with two PCI shared memory regions, since they tend
to have the second BAR ad PCIR_BAR(2). if_ndis_pci.c tests explicitly
for PCIR_BAR(2). This has been changed to simply fill in ndis_res_mem
first and ndis_res_altmem second, if a second shared memory range
exists. Given that NDIS drivers seem to scan for BARs in ascending
order, I think this should be ok.
- Fixed the code that tries to process firmware images that have been
loaded as .ko files. To save a step, I was setting up the address
mapping in ndis_open_file(), but ndis_map_file() flags pre-existing
mappings as an error (to avoid duplicate mappings). Changed this so
that the mapping is now donw in ndis_map_file() as expected.
- Made the typedef for 'driver_entry' explicitly include __stdcall
to silence gcc warning in ndis_load_driver().
NOTE: the Texas Instruments ACX111 driver needs firmware. With my
card, there were 3 .bin files shipped with the driver. You must
either put these files in /compat/ndis or convert them with
ndiscvt -f and kldload them so the driver can use them. Without
the firmware image, the NIC won't work.
prodstr may be NULL when fetched. For the default device description,
guard against this and return the numeric IDs instead when this
happens. For the matching routines, and consider NULL to not match
those entries that aren't NULL w/o calling strcmp.

and that can be used as an identify function for all kinds of busses on a
certain platform. Expect for sparc64 these are only stubs right now. [1]
- For sparc64, add code to its uart_cpu_identify() for registering the on-
board ISA UARTs and their resources based on information obtained from
Open Firmware.
It would be better if this would be done in the OFW ISA code. However, due
to the common FreeBSD ISA code and PNP-IDs not always being present in the
properties of the ISA nodes there seems to be no good way to implement that.
Therefore special casing UARTs as the sole really relevant ISA devices on
sparc64 seemed reasonable. [2]

without Open Firmware directly instead of using OF_getetheraddr(). This is
a bit painful though, as the MAC address is contained in the NA field of
the VPD of the EBus bridge, which is is another function of the same chip.
To make it worse, the VPD of the EBus bridge can't be accessed via the PCI
capability pointer but has to be digged out from the Boot PROM and has a
non-standard format.
The PCI VPD struct and macros used here should be part of the FreeBSD PCI
code nevertheless.

MAC address stored in the "local-mac-address" property of the device's
OFW node if present and the host address/system default MAC address if
the node doesn't doesn't have such a property. If set to "false" the
host address will be returned for all devices like before this change.
This brings the behaviour of device drivers for NICs with OFW support/

The man pages of the respective drivers will be updated separately to
reflect this change.
