Not willing to wait to see if the 96xx driver is ever updated, I picked 
up some cards that work with the 173 driver.  As long as I use the 
nvidia driver, all is well.  I have nvidia's twinview up for my AGP 
dual-head card, and the other PCI cards work fine, for a total of four 
screens.  I have yet to get xinerama working across all of the screens, 
but that is not a huge priority.

Interestingly, I found that I have the same issue as I had with the 
older cards if I attempt to use the nv driver.  It seems nv simply 
cannot deal with any of the PCI cards I have tried.
