Following the instructions here:

https://ask.fedoraproject.org/question/10041/how-to-repair-unbootable-fedora-install/

I did this:

mv /boot/initramfs-2.6.32-358.0.1.el6.i386.img /boot/initramfs-2.6.32-358.0.1.el6.i386-nouveau.img
dracut /boot/initramfs-2.6.32-358.0.1.el6.i386.img 2.6.32-358.0.1.el6.i386

Interestingly enough, the new initramfs that I got from this command is slightly
smaller than the one that I already had in /boot.

Sadly, this made no difference.   When I booted the machine, I still got the
same dracut warning and kernel panic.
