My understanding is basically client-only, aside from looking at the Open Graphics Project prototype rendering model a bit. As far as I can see from the discussions and models publicly available they are targeting a certain OpenGL standard for their card, although I can see I must have misunderstood what that really means. So a modern GPU is essentially a proprietary CPU with an obscure instruction set and lots of specialized texel hardware? Given the total lack of documentation from either ATI or NVidia about such cards I'd guess it's impossible for Linux to provide any kind of reasonable 3d engine for that kind of environment, and it might be better to target a design like the Open Graphics Project is working to provide.
