I think the patch has been applied on the trunk.

If this is with agpgart, try without.

If you want to work on DRI, you should get the DRI CVS, which is broken
differently and will be merged into XFree86 for 4.3.0. The driver is
broken since it's been updated for Mesa 4.0.x, and I don't have hardware
to test and fix it anymore.

If this only happens on server reset,
http://www.penguinppc.org/~daenzer/XFree86-4.2/patches/r128-indirectBuffer.diff should help. This is also on the CVS trunk already, and the radeon driver has been fixed even better in DRI CVS.
