Bug 55346

downstream bug from ubuntu, with several dupes:

https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/1053836

we do have the autobind patch from Dave applied, but these machines are not all hybrid ones, and the crash can occur on resume from suspend so it's not related to how the xserver is initialized.
