Description of problem:
Following yesterday's update via yum 2 of my machines were rendered
unable to launch X.org. I saw the threads on disabling "rhgb quiet" as
well as trying to disable DRI in the xorg.conf. Neither of these
worked in allowing X to start. The section of the Xorg.0.log
containing the error is: 



This has happened on a HP laptop (Radeon graphics) and an AMD Athlon
(Nvidia) so I don't think it's graphics card-specific. Both of these
boxes were started as FC3T2 and continuously updated.

Any ideas where I can begin attempting to fix this?

Version-Release number of selected component (if applicable):


How reproducible:
Always

Steps to Reproduce:
1. Reboot machine.
2. Choose .639 kernel (minus the rhgb quiet in the kernel params)
3. Boot will thrash when X tries to load
4. After 3 attempts to load, X presents error and lets you see the logs.
    

Actual Results:  X refuses to start, even after attempting to
reconfigure itself.

Expected Results:  X should start up.

Additional info:

(**) Option "dpms"
