Motherboard/Video Card Combo:
Biostar GF7100P-M7S (integrated Geforce 7100 chipset)
I've installed the restricted drivers, and ran nvidia-xconfig after the drivers alone didn't work. I looked in my /var/log/Xorg.0.log and found:
(--) PCI:*(0:16:0) nVidia Corporation unknown chipset (0x07e1) rev 162, Mem @ 0xed000000/24, 0xd0000000/28, 0xee000000/24
So, I looked up the chipset and found it is "almost" supported:
So I tried to force the chipset in my xorg.conf's device section:
Identifier "NVidia GeForce 7100"
#Chipset "GeForce 7100 GS"
But, neither did anything.
