nvidia linux binary driver priv escalation exploit

First up I didn't write this but I have executed it and it did work here, I was given this anonymously, it has been sent to nvidia over a month ago with no reply or advisory and the original author wishes to remain anonymous but would like to have the exploit published at this time, so I said I'd post it for them. It basically abuses the fact that the /dev/nvidia0 device accept changes to the VGA window and moves the window around until it can read/write to somewhere useful in physical RAM, then it just does an priv escalation by writing directly to kernel memory.
