"...for some reason the prebuilts for rh8 doesn't seem to be working for everybody, or anybody as far as i can tell."
And that is why I use the tarballs, at least for the kernel module, always.

I have been using Linux for 5 years, the nvidia binaries since the day they first came out, and I'll trust my own gut on things like this.
