I have this this same problem on a Thinkpad T60 running Fedora 7, running
I have a very similar X config and very similar output/log. I can upload mine
if you care.
I was using the "intel" driver, but it wouldn't support dual-head, so I switched
to the i810 driver and noticed this problem.
I'm running in x86-mode so the platform should get changed from x86_64 to All.
I'd also like to increase the severity because it means I cannot logout and

current Fedora 7 still doesn't let you restart X when using the i810 driver.
I'd increase the severity but it wont let me. This means you cannot change
users without rebooting, which makes it hard to perform certain maintenence
