Congratulations, sounds promising in total!
Acutally I noticed for a couple of times problems with external monitors:
Apply a beamer, change resolution to 1024x768 for both screens and present.
Fine so far.
Problem arises then disabling the external monitor and switching back the
resolution to 1600x900 - mostly the screen remained black, and I could not
bring it back to life. Had to switch it off.
May this be better with a newer kernel? Current version is 3.1.10-1.9-

Sound keys work, Fn-F4 as well, but no Fn-F12 (Hibernate)
