That sounds like there's a problem with the acceleration of your
video card. I can only find that print in the neomagic driver, and
it's commented out in the source. Check you have up to date source
for the kernel.

When bringing up a terminal with new hardware, it's often best to
not start aux/vga (and subsequently, rio) automatically. Comment out
the vgasize and monitor lines in plan9.ini, boot it, it should come
up to a shell prompt, then you can play with aux/vga manually, e.g.

	aux/vga -p>/tmp/x

will log in x what the curent state of the vga card is and you can
look there to see if aux/vga found any problems (unknown card, etc.);

	aux/mouse ps2

for example will make sure you have a mouse if you get the graphics
working (chnage the argument to what you have);

	aux/vga -m monitor -lpv resolution>/tmp/y

will try to start the graphics with the monitor type and size you
choose (e.g. -m t23 -lpv 1024x768x16) and also log progress and
problems in /tmp/y.
