Graphics drivers that work under dom0 actually have a pretty good chance
of also working in a suitably privileged domU, without source
modifications. Some work, some don't. Those that try to make BIOS calls
seem to be most problematic, though I guess even they could be fixed. I
think more success has been had using kernel drivers than driving the
card from X.
Give it a go, trying the various tricks that have been suggested on the
list beforehand, and then please report back. At some point it would be
nice to have concerted effort to make it work for a wider range of
graphics cards.
Thanks,
Ian
