I had tested it with a Radeon 64MB DDR and 8500, a Matrox G400, and a
Rage 128 Pro.  I didn't try pcigart.  It could work, but the BSD pcigart
support in 4.3.0 was broken and could have caused problems if you set a
larger AgpSize than default because the allocation in ati_pcigart.h
wasn't contiguous.  Conversion of drm_scatter.h and ati_pcigart.h to
busdma would be the best thing to do -- I did the FreeBSD busdma
conversion pretty quickly, but held off on it because our busdma doesn't
work well for this yet.

6) someone make a port of driglide (ports/x11-severs/driglide in
FreeBSD) to get 3dfx cards working?
