At one time I was looking to put three video cards in my
home system, but before I started beating my head against a
wall I found that GeForce cards do not work well in a
multi-card environment in Linux.  At the time, it was
guaranteed that nothing would work properly if even one of
multiple cards was a GeForce card...I have since heard that
some people have gotten multiple displays to work using
GeForce cards, but there is no rhyme or reason in what works
and what doesn't.

Note that my information on this is about a year old now, so
something *might* have changed, but it isn't likely.  No
major kernel changes in that time, and only relatively minor
updates to the NVidia drivers.  You might check out mailing
lists for the XFree86 project and see if anyone there has
made progress on the problem.

Best of luck.
