Xorg.0.log from a successful boot

Description of problem:
At about the point in the boot sequence where I would expect the modeset switch to occur the screen goes black. The boot process doesn't complete. (Though I have encrypted partitions so I would need to be able to enter some data in order to finish the boot, so it's possible that the boot process is continuing, but that I can't tell.) When I use the nomodeset parameter the boot process works as expected.

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

How reproducible:

Steps to Reproduce:
1. Boot with modeset
Actual results:

I retested this with kernel and I still get a black screen (with signal) early in the boot process if I boot with modeset instead of nomodeset.

Today I tried entering my luks password blind a couple of times and going away for 10 or 15 minutes to do some other stuff. When I came back I had a normal working gnome session. I tried switching to a vt and while a switch occured, the graphics in that mode were messed up. I had specs of white on a mostly dark screen. When I typed stuff, the specs changed. I switched back to X and my gnome session is working OK.
I currently have installed:

Thinking about it I thought it might also be useful to mention that I do not use the quiet or rhgb kernel parameters when booting. For testing I was using the kernel with the following parameters:
elevator=deadline modeset crashkernel=256M

I retested this with today's koji updates (xorg-x11-drv-ati-6.12.2-11.fc11, mesa-7.5-0.14.fc11 and kernel-PAE- and am still seeing the same symptoms.
Comment 6 Bug Zapper 2009-06-09 10:03:36 EDT
This bug appears to have been reported against 'rawhide' during the Fedora 11 development cycle.
Changing version to '11'.

This is no longer happening in rawhide (F12).
