Hey I just did this a little bit back. You go to NVIDIA.com and choose the Drivers section. Look for your card and you should run into a driver called
Linux IA32 Go download that file and put it anywhere you like. Then follow the instructions at this link ftp://download.nvidia.com/XFree86/Linux-x86/1.0-4496/README.txt to finish it off. Note that the file as XFree86Config that they refer to is really XFree86Config-4. Be sure not to get them mixed up.
