With -rc2 on F13, x86_64, Dell E6400 I had X not showing
 on "startx" at the first attempt (totally blank screen), with
 the oops pasted below found after Alt-Fn'ing into another
 console tty and logging in.

startx worked on 2nd attempt, and I was able to work for
 a while (at least 15 minutes), then on exiting the Gnome
 session the laptop locked up hard (CapsLock did not
 change LED upon press), and I could only keep power
 button pressed to turn the computer off.

[root@...f linux-2.6.35-rc2]# grep KMS .config
CONFIG_DRM_KMS_HELPER=m
CONFIG_DRM_I915_KMS=y

-rc1-git2 and earlier have had no such issue.

The "taint" P flag is due to the broadcom-sta driver that
 I compiled for my BCM4322 wireless chip (and have for
 the last several dozens of kernels).
