Same problem on Ubuntu Gutsy (Kernel 2.6.24-4) on Thinkpad T60 with ATI Radeon X1400
and ATI's fglrx v8.01, and Compiz.

When LIBGL_ALWAYS_INDIRECT is set (default, unfortunately):
- glxgears: a bit choppy at fps=3500
- fgl_glxgears: Segmentation fault

When LIBGL_ALWAYS_INDIRECT is unset (manually in a terminal):
- glxgears: works at fps=4200
- fgl_glxgears: works at fps=900 (without window decoration, though)

Compiz works smoothly; suspend/resume works also.

A separate fix would be to fix the "segmentation fault" in fgl_glxgears and replace it with
an informative error message about LIBGL_ALWAYS_INDIRECT
