What kind of graphics chip is that?
Are you sure you are using the radeonhd driver from the xorg-x11-drv-radeonhd package? (As opposed to the radeon driver from the xorg-x11-drv-ati package)
What package versions of kernel, Xorg driver are you running?
Any log files?
Is the issue reproducible by running "Xorg :2" from a root console login shell?
Can the issue be worked around by booting the kernel with the "nomodeset" parameter? Note that the radeonhd driver only works with nomodeset.
This bug appears to have been reported against 'rawhide' during the Fedora 11 development cycle.
