Running 'cat all those files >/dev/null' hangs/crashes my system (I had only rhythmbox, firefox + a couple of gnome-terminal windows open). This hang occurred with a newly built/booted Fedora kernel-3.7.1-1.local.fc19.x86_64 (above patch included). Here is the dmesg spew. Let me know if the i915_error_state would be helpful.
