only supports dual head on g80 (that's 8xxx and 9xxx). If you want dual
head on older stuff, you need nouveau.

I have a machine with 2 ea. nVidia Quadro NVS285 dualhead cards, so a
total of 4 monitor connections.  I'm trying to figure out the best way to
connect 4 monitors without making the machine too unstable.  The binary
blob drivers aren't the most stable in the world.... But I really need
XvMC and 2D acceleration for Mythtv.  I would ideally want 2 mythtv
displays and 2 user displays (non-accelerated is OK for this), each with
its own login.
