Xorg log file

After upgrading intel drivers from 7.11 to 8.0 on Arch Linux, the X server crashes on start if two monitors are connected (laptop plus external screen), with this in the log:

[ 9.047]
[ 9.047] Backtrace:

[ 9.047] Segmentation fault at address (nil)

Fatal server error:

In my case, I don't even get to see the GDM login manager; others seem to have similar problems as soon as gnome-session starts:

I am not sure if the Intel driver is the problem; the launchpad bug suggests it's evdev but I am not experiencing the same behavior as described in that bug. I have also tried installing xf86-input-evdev-git, which didn't help. Only "solutions" so far:
- downgrade to 7.11,
- don't use external monitor
Using the vesa driver, the X server does not crash (which indicates that the intel-drivers are in fact causing the problem), however the screen looks pretty garbaged with vesa.

Complete Xorg.0.log is attached; please let me know how I can provide further useful information.
