Jon, and Bob.
It would be great if you could get this chipset up running.
Just to let you both know, the 3D engine is completely different 
compared to the other unichromes. I've tried to request docs from VIA, 
but nothing so far.

This means that we probably cannot get EXA composite working nor can we 
get accelerated OpenGL to work.
