Not the slightest idea. I don't understand what your code is doing
either, I only bisected it in order to get a running linux-next
kernel.

The machine is very much alive, but the screen output is garbled. On
the text console, it shows a couple of characters around the cursor
position all over the screen. In X, it seems to be similar. The kdm
login screen gets shown as a nice pattern of colours, and they
change when I move the mouse. I can't identify anything visible on the
screen though.
Trying with i915 KMS next.
