No, Tait, unfortunately, it didn't solve the problem.
But I did find the reason the nvidia driver wasn't working for the G100:
not enough virtual memory. Adding vmalloc=256m to the grub boot line
licked that problem. It probably was not working for whichever chip was
second in the list but I didn't experiment.
After getting nvidia driving both chips, I ran nvidia-xconfig and it
generated a new xorg.conf. That one locked up the entire machine! All
screens dark, even the keyboard stopped working.
FWIW, here is the present xorg.conf, which only lights up one monitor,
and the one which locked up the entire system. Not much difference.
==Current workable xorg.conf==
