I know you can do this in XP because I've seen it. It would depend on  
the hardware actually having separate DAC LUTs for port, and a driver  
that took advantage of it. What I can't remember is the user  
interface; whether it shows up as though it's a single card but has  
two color management tabs to associate separate profiles for the two  
displays; or if it shows up in UI as though it's two separate video  
cards.
