I've tested your patch and it runs smoothly on my machine.
However I had several NULL pointer dereference BUGs that happened when I 
left X or rebooted my system. I think this is caused by your patch. 
There is nothing in the logs unfortunately, but I scribbled down the 
following by hand (not the whole trace, I'm too lazy):

BUG: unable to handle NULL pointer dereference at 0..038
