on big-endian archs like sparc64, e.g.:
uart0: <16550 or compatible> at port 0x3f8-0x3ff irq 43 pnpid @HEd041 on isa0
is now correctly printed as:
uart0: <16550 or compatible> at port 0x3f8-0x3ff irq 43 pnpid PNP0501 on isa0
There are probably other endianness issues lurking in the PnP code which
however aren't exhibited on sparc64 as the PnP devices there are sort of
PnP BIOS devices rather than ISA PnP devices.

and do some preparations for handling 12x22 fonts (currently lots of code
implies and/or hardcodes a font width of 8 pixels). This will be required
on sparc64 which uses a default font size of 12x22 in order to add font
loading and saving support as well as to use a syscons(4)-supplied mouse
pointer image.
This API breakage is committed now so it can be MFC'ed in time for 6.0
and later on upcoming framebuffer drivers destined for use on sparc64
and which are expected to rely on using font loading internally and on
a syscons(4)-supplied mouse pointer image can be easily MFC'ed to
RELENG_6 rather than requiring a backport.

Now that Giant is acquired in uprintf() and tprintf(), the caller no
longer leads to acquire Giant unless it also holds another mutex that
would generate a lock order reversal when calling into these functions.
Specifically not backed out is the acquisition of Giant in nfs_socket.c
and rpcclnt.c, where local mutexes are held and would otherwise violate
the lock order with Giant.
This aligns this code more with the eventual locking of ttys.

of whether or not Giant was picked up by the filesystem. Add VFS_LOCK_GIANT
macros around vrele as it's possible that this can call in the VOP_INACTIVE
filesystem specific code. Also while we are here, remove the Giant assertion.
from the sysctl handler, we do not actually require Giant here so we
shouldn't assert it. Doing so will just complicate things when Giant is removed
from the sysctl framework.
sleep lock status while kdb_active, or we risk contending with the
mutex on another CPU, resulting in a panic when using "show
lockedvnods" while in DDB.

control register and AGP bridge seems to be inconsistent with some BIOS.
Instead of relying on BIOS settings, we just take the initial aperture size
and encode them for both miscellaneous control register and AGP bridge.
Some idea was borrowed from agp_nvidia.c.
- Add preliminary ULi M1689 chipset support. The idea was taken from Linux
because hardware and documentation are unavailable. Not tested.
- Add more VIA chipset PCI IDs taken from Linux driver.
