NVidia calls it TwinView, XFree's version ix Xinerama. The config below is for 
Xinerama, the TwinView stuff is commented out. Both Screens (DFPs in this 
case) are connected to one card, it's a GF5700 AGP with two DVI ports. I'm 
running this on i386.

TwinView has one advantage: it's possible to assign nvidia-settings to both 
screens. The downer is, applications and your window manager don't recognize 
the two screens. To them, it's only one very-wide screen. With Xinerama you 
can eg. maximize to only one screen and KDE panels (GNOME ones as well I 
guess) can be assigned to exactly one screen. In my case this outweighs the 
benefits of TwinView.
