Same here on a ThinkPad-Edge-E330 with a kernel 3.5.0-26-generic.
Without adding "915.i915_enable_rc6=0" to boot param graphic freeze, accessing trough ssh is still possible.
By adding this option the system graphic hang for few second and still almost usable (I've notice some text missing, probably memory corruption, but we are still able to "click" and reboot graphically).
A quick step to produce the bug: run glxgears and wait about 1 minute.
Note that I'm still able to login to the laptop with ssh, and since this bug is marked as "incomplete", tell me what information you need (like memory dump) and the way to get them, I will provided.
