Video driver:

xf86-video-intel-2.17.0_1

(used to be 2.7 I think).

r244122

I got a lot of Linux hits on different forums so maybe this is a i915kms 
thing but it's still funny it worked with 10.0-current, a lot of manual 
patching and experimental xorg-ports a year ago but not now with 
9.1-release and  WITH_KMS=YES + WITH_NEW_XORG=YES.

As I said it's just the screen that doesn't wake up. SSH works and I 
managed to verify so does the keyboard.
