External / 2nd Monitor support


Has anyone heard anything about external / second monitor support with OSX?

I have a Powerbook and hook up a 21" monitor at work as my main screen and use the PB monitor for the little things (AIM, SoundJam, Etc). At home, I park my closed Powerbook underneath the tripod of the 17" studio display which is hooked to the VGA out in the back.

Unfortunatly, as it is now, OSX will not start up in either of these situations. ACK! I want to use OSX, but really can't do without the second/larger monitor. Does anyone have any idea on the difficulty/probability of a third party coming out with a solution to this problem before Apples final release. I would imaging that there are many more power users out there who are wanting the same.
