Xorg.0.log for ATI Radeon X800 without xorg.conf

glxgears works (though slowly) only if "nomodeset" is NOT specified.
x86-64 system with all latest rawhide updates (15 April 2009)
Radeon X550 PCI express.

Changing version to '11'.

For current F11 w/updates including packages
"glxgears" works as expected.
