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.
