Have you applied the r200 copy-pixels patch[1] to your mesa
installation?

With that patch my Radeon 9000 can handle Xgl/Compiz pretty much ok.
With large windows on a resolution larger than 1024x768 it gets a bit
slow, though. Video playback is unusable slow and OpenGL doesn't work
but that's expected, as far as I know, as long as mesa/r200 doesn't
support pbuffers.
