When plugging in my u2133H Dell Monitor, radeon driver appears to detect the
monitor and the gnome workspaces are extended with the resolution of the
monitor (1920x01080).

However, the Dell monitor stays blank and ``Enters power saving mode''. The
monitor does work on Windows.

Card: R700, ATI Mobility Radeon HD 4670.
01:00.0 VGA compatible controller: ATI Technologies Inc Device 9488

DDX from (recent) git. Kernel 2.6.38-rc8. Xorg server 1.9.4.
