i've updated the bios to A06, and am using kernel 2.6.37.x (5/7/8) from
kernel ppa.
From what I can tell, it works fine, but I need to test more...
for now I have working screen when not in docking station, and I have cloned
screen with both displays working when in docking station....
but i need to test more to confirm this isn't just a fluke....
