Hm. Following the cryptic references in the RH bug, it's possible that
there's a kernel commit that would fix this:
commit 1cfa49c2f1f3f42cf166438c17dafac577610836
Author: Ben Skeggs <bske...@redhat.com>
Date: Tue Feb 9 16:59:26 2010 +1000
drm/nv50: EVO uses a real ring buffer, not jumps back to start like PFIFO
Tested on NV84GL and NV96 with cursor state caching disabled to force
lots of EVO use, no problems seen.
There's been some reports of EVO randomly dying and reporting an error
during cursor state changes for some people, I've been unable to
reproduce on my hardware but hopefully this is the culprit.

I thought we had that in our tree, but it seems that we don't.
