Wink Saville e40c67597e [PATCH] Patch for nvidia divide by zero error for 7600 pci-express card 
The following patch resolves the divide by zero error I encountered on my
system:

	http://marc.10east.com/?l=linux-fbdev-devel&m=116058257024413&w=2

I accomplished this by merging what I thought was appropriate from:

	http://webcvs.freedesktop.org/xorg/driver/xf86-video-nv/src/
