Your bes bet would be to download the tar files at nvidia's archives and compile the drivers by yourself. Get the release notes for that particular version, READ THEM, and be sure to have the following installed:
you can check out those with the following command (for example):
rpm -qa | grep gcc
If you don't have ANY of them, get them from the installation CD's (example):
rpm -ivh kernel-source[blahblahblah].rpm
If everything is on place, start a console only session (if you're running X):
Login as root.
Type: init 3 <----------This will shutdown X
Go to your nvidia driver's folder.
tar xvzf NVIDIA_kernel[blahblahblah].tar.gz
tar xvzf NVIDIA_GLX[blahblahblah].tar.gz
Config your XF86Config file if you haven't done so.
Use the source, Tux.
