* Monitor is a DVI monitor connected to an active mini-displayport to DVI
adaptor.
* Output to all three screens functions in Windows.
* dmesg output and xrandr output are able to see the display and print out the
correct supported resolutions
* HDMI and DVI output are functioning correctly on the card.
* Using xrandr I'm able to get the X server to think that the display is
present and functioning. (I can place windows and the cursor on the screen)
* The display is in power-saving mode from the moment that the framebuffer
console initializes. I'm not able to get any image on it.
