Does X die and leave whatever was previously displayed on the screen? I 
had a problem with an Intel 865G card a long time back. X would actually 
abort and the screen would not reset until the Graphics card is reset by 
a system reboot.

The space xxx wanted yyy error sounds familiar with one system that I 
tried running two different video cards on. The error could have been 
from an Intel graphics using one graphics card. Regardless this sounds 
like a problem introduced into the newer version of the driver.

Did you add lockup or was this part of the excerpt from the log.

Which driver are you using? (i810 or intel)

noof was a good one for my testing on an Intel driver where X crashed 
but left a residual display on the monitor.

I think that you might get away with downloading the fc6 version and 
reverting using rpm and the --oldpackage argument to see if it is 
specifically caused by  changes in the driver.

Hopefully you only need to revert the driver. File a bug report for it 
if the reverting to the older driver helps. Otherwise you might have 
problems with some other X package which brings out the bug with the 
Intel driver.
