Probably not the problem, I assume the card is there but not being
used?. The problems I know off are with radeon, mga and r128 drm drivers
(the kernel drivers for video acceleration).

Which drivers are you using for this card?

One quick test you could do is turning off acceleration in the X
configuration file (/etc/X11/xorg.conf), the option is "Options
NoAccell", I think. Video will be slow but maybe that will help know if
the video card is at fault.
