In my previous position, we used the NVidia NVS-400 quad head cards on SL 
4.4. I have attached my notes from that setup below, it might help you, but I 
think they use different drivers if I read the NVidia pages correctly.

The last driver I did this with was:

NVIDIA-Linux-x86-1.0-8774-pkg1.run

So it is slightly out of date. (as you can tell from the resolution as well 
;-) )

You might have better luck with the drivers available from atrpms, ones 
matching your config from the list:

yum list nvidia\* --enablerepo=atrpms

I don't remember why I didn't use these at the time, probably just ignorance 
on my part.

Cheers and good luck.
