i have used geforce cards with multimon....was actually a geforce and a
trident combo...i could not use the nvidia driver, but if i had 2
geforce cars i bet i could. I had to use the nv driver because the
nvidia driver would mess up the trident driver...from looking at the
nvidia site....the new linux drivers can handel up to 16 monitors. I 
have looked at the black box archives and it appers as if bb's support
for xinerma is not the greatest. But none of the threads mentioned 
what version of bb they were using...it also appears as if you have to
compile bb with --enable-xinerma, i dont know if the rh7.2 rpm has this
enabled.
