The following is better, but the cursor problem has me stumped.
All the register values look correct but it's as if the cursor
were transparent. I suspect that's the case and the cursor image
is being picked up from somewhere else in memory.

03-Sep-97 cmd/aux/vga
=====================
The following change allows the ViRGE/VX cards to work at 640x480x8 and
800x600x8. Unfortunately the hardware cursor refuses to work at 640x480x8,
no idea why.

a% yesterday -d virge.c
diff /n/dump/1997/0903/sys/src/cmd/aux/vga/virge.c virge.c
131c131
< 		if(vga->mode->z == 8)
---
> 		if(vga->mode->x > 800 && vga->mode->z == 8)

Charles Forsyth is correct in noting that 640x480x8 doesn't work
properly. If no one else has figured out why then I'll have a look
when some more pressing matters are resolved.
