for multiple useful testing cycles, and Ralf Wostrack for the final fix to get
it working.

chipsets, based on Linux's via-agp.c. On boot, the system selects which AGP
version to use based on the inserted card. If v2 was chosen, the chipset
needs to be programmed with the v2 registers still. Also included in kern/69953
are changes to make the programming of the v3 registers match linux, but that
will be left out until the need to do so is confirmed (want specs or a tester).

registers, so add a register offset array to the softc. We key off the
device ID to determine which set of register offsets. Currently the 8385
host bridge used on amd64 is the only bridge to use the AGP3_VIA_*
register offsets and all other bridges use the AGP_VIA_* offsets. It is
currently unclear if the AGP3_VIA_* offsets are for VIA bridges that
implement AGP 3.0 bridges or just for amd64 bridges.

for some adapters, at least it doesn't hang the system now. Input would be
appreciated.

associated patch to XFree86 allows the X server to work with this chipset
on FreeBSD. Additional work will include porting the Linux 3D driver.

tested on Intel BX chipsets only. The other agp minidrivers are totally
untested.
The programming api is a subset of the Linux api and is only intended to
be enough for the X server to use. There is also an in-kernel api for the
use of other kernel modules such as the 3D DRI.
