Hi

This happened to today probably in the moment, LCD was turned off by
Xserver as a screenblank
My hw is Lenovo T61  4GB, intel driver.

Seem to be related to:
https://bbs.archlinux.org/viewtopic.php?id=124900

However my machine is good old C2D - no SandyBridge in my case.
xorg-x11-drv-intel-2.16.0-2.fc17.x86_64
xorg-x11-server-Xorg-1.10.99.902-1.20110818.fc17.x86_64
3.1.0-rc5 (with my 8 unrelated patches)
