Tested this patch on my albook (PowerBook5,2 Mobility Radeon 9600 M10).
Dualhead works nicely now :)

I've been testing the xvideo overlay. When running in clone mode, the overlay
on the second head only works when the lcd is in it's native resolution. But
unfortunately the panel has some ugly lines on it then, looks like a timing
thing.  When not running in cloning mode the overlay on the second head only
works in 24 bit dept, not in 16.

Also the first time i started the patched Xorg, the second head had very wrong
colours. But i can't reproduce that anymore..

Thanks for your work ! It's making me very happy :)
