I managed to simulate the same behaviour also in Arch. It happened after I've installed gnome-extra stuff. I also noticed that udev is eating like 5-15% of CPU. I run the `udevadm monitor` and saw this: KERNEL[1259129717.200097] change /devices/pci0000:00/0000:00:02.0/drm/card0 (drm) UDEV [1259129717.209746] change /devices/pci0000:00/0000:00:02.0/drm/card0 (drm) KERNEL[1259129717.218808] change /devices/pci0000:00/0000:00:02.0/drm/card0 (drm) UDEV [1259129717.225593] change /devices/pci0000:00/0000:00:02.0/drm/card0 (drm) ... repeating fast.
After some googling I found a workaround by using Option "NoDRI" in Device section of xorg.conf, however that's not a solution.
