fixing the doubled buffered issue is pretty easy (I think I even have
a patch somewhere), but the main problem is that r128 does not support
rectangular textures, so even if you switched the default visual,
compiz or beryl will fail on the lack of rectangular textures.  You
could probably get something working by implementing glucose support
for r128, but that's still experimental at the moment.
