The latest Fedora specs have diverged a bit from RHEL5, but they're similar 
enough those docs do still at least mostly apply, and once we've iced 5.1, 
they'll get more similar again. (Many of the recent changes made to the 
Fedora kernel spec have been ported for the RHEL5 spec, but won't go in until 
after 5.1 development is finished).

By simply passing '--define "rhel 5" --define "dist .el5"' along with the 
rpmbuild line against the latest Fedora 7 kernel spec, you should wind up 
with a 2.6.22.1-based kernel with a RHEL5-ish kernel .config dropped into 
place instead of the Fedora one (or just build w/the Fedora one). You'd 
definitely have to edit the spec to add the modified nfs bits, and possibly 
edit config-generic or config-rhel to set any new .config options.
