I have a test SL 6.1 system on an old thinkpad x31 laptop using the 
ELRepo kernel-ml-NONPAE produced by Alan Bartlett.  I got there in a
roundabout way, starting from the netinstall instructions at 
http://scientificlinuxforum.org/index.php?showtopic=621 and then 
upgrading to 6.1 and replacing the old nonpae kernel with the ELRepo 
kernel-ml-NONPAE.

I'd like to produce an installation disk for SL6 with the ELRepo kernel 
for installing on other, slightly less old but still nonpae, hardware.
I've installed revisor, but can't find a way of convincing it to accept 
the ELRepo package as a kernel.  I get an error message "No Package 
Matching kernel.  This is a required package."  This is in spite of 
includepkg=kernel-ml-NONPAE
in the elrepo-kernel section of my config file and
kernelpkgnames=kernel-ml-NONPAE
both there and in the main section.  I've also replaced "kernel" by 
"kernel-ml-NONPAE" in the kickstart file and "kernel-headers" and 
"kernel-firmware" by their "kernel-ml" counterparts.

Google turns up a couple of other people with similar problems, but no 
solutions offered.

Any guidance?
