I do not know exactly how far this discussion has progressed, since I have
lost some mail recently and may have missed out. I apologize if my advice
has already been given and rejected.
I experienced the exact same problem when installing a devfs capable
kernel before installing the devfsd daemon. I use Debian, so I do not know
where or how to find devfsd with redhat/RPM. Try installing devfsd and
then rebooting one of the new kernels.
