any way to do this without rolling my own kernel?  I use the one from atrpms.

not upset about it, just mentioning to show that even with glxgears
using all the CPU power, it is still very crappy results.

[mythtv at localhost ~]$ glxinfo | grep direct
direct rendering: Yes


I use the openGL painter, and have no problems with it (although it
seems a touch sluggish)

Using XvMC also, can confirm with having to do the hack to get a color
OSD (otherwise it is greyscale).

Sorry for the dump, but here is what xvinfo gives me:
