The nvidia driver does not yet support XRandR 1.2 only 1.1.  So it does not 
support many of the things that are needed for color management with more than 
one monitor.  On the other hand the nv driver does have XRandR 1.2 support for 
SOME but not all nvidia hardware.  Of course the nv driver has no 3D support.
