mode setting a tiny bit faster as well.

I've got a couple more changes to work on today:

1) re-train the monitor when it gets unplugged and then plugged back    in. Right now, if you kick the cable out, you're stuck fumbling    around in the dark trying to run 'xrandr' again.

don't you do this already? both radeon/nouveau handle DP replug fine, I thought Intel would have been where I stole the code from.

There is some code to handle the interrupts, but I'm not sure if it's wired up. I think we rely on polling right now.
