	Well, spent lunchtime fiddling. I ended up going into nvidia-settings, 
switching it to Seperate X Screens. Then I tweaked one   monitor section 
in xorg.conf (DFP-1, the right monitor now)
Option "RandRRotation" "on"
Option "Rotate" "CW"
...and enabled Xinerama.

	So now I got the displays oriented the way I wanted, DFP-0 (left) in 
landsacpe; and DFP-1 (right) portrait.
Course, the fun Compiz stuff is gone...

	Any ideas if I can get the monitor layout I want with Copmiz working?
