Since nothing has changed in the Radeon drivers or X server,
libGL, DRI drivers, etc. whatsoever in a long time, it is highly
unlikely that any performance loss is an XFree86 driver induced
problem.

Oddly enough, Ingo Molnar, and several other people have remarked 
to me this week that OpenGL performance has magically sped up 
dramatically lately.  I haven't changed anything which would 
change performance up or down, so I'm surprised anyone sees any 
difference at all.  My guess is something in the kernel changed.

Personally, I see no change in performance either way.

I have been checking out the GL screensavers since the original release
and this last release has actually worked better. The screensavers have
been choppy but now they are are a lot better, smooth and no choppyness.
My machine is an older pIII 600 and a I810 video with 256 megs of ram.
