I have the same problem. I don't think it's good for the monitor, so I'll disable power saving for the time being.
My monitor is a "DELL P2411H" (from Xorg.0.log), and the X driver is Radeon. The monitor is connected via the DVI cable. I don't have the problem when I use fglrx, the proprietary AMD driver.

Searching the Redhat bugzilla I assume the equivalent bug is this: https:/ /bugzilla. redhat. com/show_ bug.cgi? id=714334 (the link in Tim Cuthbertson's bug description is missing the id)
