I've tried the latest git again last week (979ad04d) and this still doesn't
work.  Even worse, if the external DVI display is attached via the HDMI
connector on Xorg startup, the local display now goes blank as well.

On the postivie side, I discovered by accident that if I close the lid of my
laptop on boot up the BIOS will enables the external DVI display plugged into
the HDMI port (which lasts until Xorg loads, at which point they both go
black).

Anyway, I would love to do a registers dump from the console (using rhd_dump)
for you guys in this state (i.e., after this BIOS has successfully enabled the
external DVI display plugged into the HDMI).  Are there any registers in
particular it would be good to know the state of?

Thanks!  -Tyson

PS:  With regard to comment #5, I've tried every combination of enabling and
disabling combinations options via xrandr (VGA, DVI, and HDMI) and have never
managed to get any display on any external display other than one plugged into
the VGA port.
