I left this machine running overnight with the X process at 100%.  The 
next morning the following lines were appended to Xorg.0.log...

(EE) RADEON(0): GetBuffer timed out, resetting engine...

I opened the case to confirm the graphics card type (ATI 9250 / 128 MB 
DDR TV-out DVI 64-bit).  When I did this I noticed the fan attached to 
the heat sink was frozen.

My new guess is the card would overheat when the X server started.

Does this seam reasonable?

I've ordered a new ATI graphics card.  This one just has a heat sink (no 
fan).  I picked ATI over NVidia just to try the new Fedora ATI drivers.

I had a similar "fan lockup" problem on other NVidia and ATI cards.  If 
this is the problem, does anyone know where I can purchase a replacement 
fan?  It seems like a waste to throw the card away.  It works at run 
level 3.
