I have an rv280 based card and an rv530 based card that I am using in
rawhide. Things are currently changing often. When things are working
well I get significantly better frame rates out of glx gears than previously.
(About 1000 fps on the 280 and 3000 on the 530.) But when things don't
work correctly things don't work or are very slow. Usually changing whether
or not I use the nomodeset parameter fixes things. I also see lockup problems
with the 280. It is common to need to do a C-A-BS or several to get a display.
leaving glxgears running for about a minute will generally lock up X in a
way that requires a reboot (I don't know if the kernel is dead, it might
just be X) to fix things.

With a lot of active development going on it's hard to say how things will
look for F11 final. My guess is that things will really be nice around F12
time. I don't usually use compiz or flash, so I don't have specific info
about those.
