This was quite interesting, but didn't work.  When I took out Load
"GLcore" and Load "dri" from the module section of
/etc/X11/XF86Config-r I got an error message with glxgears:
    ~$ glxgears
    Xlib:  extension "XFree86-DRI" missing on display ":0.0".
    979 frames in 5.0 seconds = 195.800 FPS
The threads in that url seem to think it is a problem with X.  What
puzzles me is that it works fine under 2.4.16 but not under 2.6.6, but
they use the same XF86Config-4 file.  Thanks,
