The one in /usr/ports/x11/nvidia-driver-173. I have to use this for the aging 
FX 5200.

I'm rendering a whole bunch of molecules (spheres), moving a camera and at the 
same time doing quite a bit of CPU intensive numerical integration of a whole 
slew of coupled ordinary differential equations -- I need the speed of the GPU 
(read proprietary driver) to relieve the CPU and avoid a slide show. (This 
works very nicely with dual core CPUs: I use one thread for the rendering and 
another for the numerics.)

I'll keep digging (and getting educated, I guess). Incidentally, in Debian 
GNU/Linux they have a system of clever "diverts" which avoid these kinds of 
library clashes. 

Thanks
