When you used the atombios_support branch you forgot to set the option:
Option "UseAtomBIOS" "True"
Thus you are using the same mode setting as the other driver, therefore I
expect the same behavior regarding the external DVI.
Maybe you can retest with the option set. I would like to see if this makes a
difference for the native 1900x1200 display mode.

Sorry for the delay, long weekend in Canada :)

I tried out the UseAtomBIOS option. When I run plain X from the command line I
see both my laptop *and* external DVI light up! The resolutions are whacky,
especially on the external DVI. See comment #37 for the xorg log.

However when I log into my gnome desktop using atom's a good news and
bad news thing.

Good News: My external DVI monitor lights up with 1920x1200 resolution this

Bad News:

1) My laptop panel doesn't light up anymore. I tried turning it on manually
with xrandr and it says:

xrandr --output PANEL --auto
xrandr: Configure crtc 1 failed

2) The external DVI display has some horizontal flickering problems. It's not
unusable, but annoying.

I will attach the xorg log from logging into the desktop. It's quite different
at quick glance. Not sure why again.
