If you know a bit of what you're doing, you can rebuild the kernel from
redhat's source tree. I believe that they place their conifg files in the
docs directory (/usr/share/doc/kernel-something ).

Keep in mind that RH (and Mandrake, and SuSE) already include some of the
most necessary patches.

However, adding a patch of your own can be a tricky business.

A couple of monthes ago I suggested to modify the kernel SRPM and run 'rpm
-bp' to get the source tree with the modifications. But I realize now that
trying to add yet another patch there may not be easy.
