3.4-stable review patch. If anyone has any objections, please let me know.
------------------ From: Dave Airlie <[email protected]> commit 3a75885848996baab5276ff37ebf7295c3c753f0 upstream. Otherwise when X starts we commonly get a black screen scanning out nothing, its wierd dpms on/off from userspace brings it back, With this on F18, multi-seat works again with my 1920x1200 monitor which is above the sku limit for the device I have.
