I just booted the LiveCD as is on the RV200.  KMS was enabled and the
speed wasn't a problem.  It had other severe rendering/shading issues, plus
something I did completely hung the box.

Getting back to RV250/280, I saw that Red Hat BZ 679579 has a reference
to freedesktop BZ 34280, which sure looks like the same problem (at least
in the tuxracer example).  More importantly, one of the guys there has a
patch against mesa for it which seems to work for him.  Perhaps that could
be investigated to find out if it applies to Gnome as well?
