Dump of xrandr showing incorrect activation of DVI-0 after patches

The "xrandr --verbose" dump following booting up with the patched 2.6.36 kernel
(both patches in this report and the last one in 18564) and the the DVI monitor
plugged in via the HDMI port.

Nothing is plugged into the DVI port (I don't even have the docking bay that
exposes it), but you can see how the system lists the monitor under both HDMI-0
and DVI-0 and has tried to activate it under DVI-0.

To properly activate it, I have to turn off DVI-0 and on HDMI-0 manually using
xrandr (dump is called pre-switch because I haven't done this yet at this
