Description of problem:
After installing/configuring FC6 on a Dell PE2850, dual Xeon, Radeon RV100 QY [Radeon 7000/VE], things were all happy until I installed the xen kernel. Rebooting with the xen kernel results in X using 100% of the CPU, displaying nothing, and logging
(**) RADEON(0): Idle timed out: 64 entries, stat=0x80010140
(EE) RADEON(0): Idle timed out, resetting engine...
(**) RADEON(0): EngineRestore (32/32)
repeatedly. I've tried various xorg.conf settings without any luck. I'll attach some logs and configuration files.
