I also re-installed everything on this laptop twice (because I was also working on other things). Despite all of the tweaking, there was very little change overall in performance. fglrx = slow radeonhd = faster, but somewhat problematic (3D stuff/compiz don't work well) radeon = a little slower than radeonhd and limited in capability (2D only) At least that's the case for me. I'll keep trying, but for now I've renamed my xorg.conf to a backup file and switched back to Intel graphics. While less than ideal, at least Compiz loads and more of the 3D stuff runs...
