Same here..I had to recompile the kernel (initrd) without rivafb/nvidiafb
and then the Nvidia driver started to work

You're missing a step. The nouveau module is already in your existing
initrd, where it will be loaded *before* your root filesystem is mounted,
*before* the blacklist file can be read. You have to rebuild your initrd
after adding the blacklist entry. I've done this. I know it works. Later
kernels will get installed and have their initrd generated with the
blacklisting already in place, and their initrd won't have nouveau.

Package distributor. I believe RPM Fusion's nvidia drivers include either an
/etc/modprobe.d/nouveau.conf or nvidia.conf for this purpose.

Wasn't offended, just saddened that all the hard work being done to create a
free and open driver that Just Works gets stomped on because it made it
harder to install a 3rd-party binary blob. :)
