When I try to start Xorg, both via gdm on startup, starting gdm myself and running startx, I get a Signal 11. It doesn't give me any (EE)s in the Xorg.log, only (WW)'s that I don't think looks like something making it crash by the looks of the backtrace. Reproducible: Always Should have startet gdm to login

Does X work with the nv or vesa video driver?
No neither nv or vesa worked. Same traceback.
And have you updated to xorg-x11 7.2 yet? Does that make a difference?
Haven't updated since the flaw. I'll try to get update over the weekend and get back at you.
System updated to 7.2, still no fix.
Which version of evdev are you using? Does it help to disable the evdev driver?
After switching from evdev too the older mouse driver, it worked. I tried recompiling evdev, where media-fonts/encodings x11-wm/twm sys-apps/coreutils package net-misc/netkit-rsh and x11-terms/xterm. I believe evdev wasn't updated just recompiled with the version being -1.1.5-r1. So bug solved.
As you say, bug solved.
