How would that make any difference?

I did not recreate initramfs, but I have updated kernels since initial install 
(which will recreate initramfs).  All I did is:
1. Install nvidia from rpmfusion, which adds /etc/modprobe.d/blacklist-
nouveau.conf
2. Add  rdblacklist=nouveau to grub.conf

To be sure, this procedure could be retested on a new install, since I can't 
prove that it isn't the initramfs caused by a kernel update that makes it work 
here.
