I don't know if anybody is following my story here but I noticed an xorg-edgers kernel update from 3.5.0.3.3 to 3.5.0.4.4 today so I thought I would give it a test running Unity. Note, as my previous comment I can run kernel 3.2 forever without issue. So I upgraded and rebooted to 3.5.0.4.4 and I still see PFIFO_CACHE_ERROR nouveau errors but this time my system does not lock up. I don't see any UI problems. Here are the dmesg logs:
