Actual results:
glxgears shows green flashes on a black background.

Radeon X550 Xorg.0.log

my system behaves identically.

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.
Comment 3 Joachim Frieben 2009-04-15 01:11:43 EDT
To be more clear, other GL applications like screensavers are affected, too.
Comment 4 Bug Zapper 2009-06-09 09:25:00 EDT
This bug appears to have been reported against 'rawhide' during the Fedora 11 development cycle.
Changing version to '11'.

More information and reason for this action is here:
Comment 5 Joachim Frieben 2009-09-09 01:10:24 EDT
For current F11 w/updates including packages
- kernel-
- mesa-*-7.6-0.1.fc11.i586
- xorg-x11-drv-ati-6.12.2-18.fc11.i586
- xorg-x11-server-Xorg-1.6.3-4.fc11.i586
"glxgears" works as expected.
