I never tried it but it likely Just Works(tm) on any of the ATI-based  
cards and maybe the PGX32 as well.

Someone(tm) needs to make the kernel part of DRI work, it's in the  
source tree ( at least for ATI chips ) but the code is rather x86- 
specific and doesn't even work on macppc.

Not sure what's missing for XVideo, but as far as I know the Creator  
supports only 8bit overlays and I seriously doubt it would do things  
like motion compensation or YUV->BGR conversion.
Also, the Creator3D doesn't support texture mapping at all so its use  
would be a bit limited.

have fun
