Thanks for the advice. I was building the RPM on a server that used a
different architecture. This probably was the source of the problem. I
rebuilt the RPM on a machine that used the same architecture as my target
machine and I also used kernel-devel and I am now able to load the madwifi
RPMs for my custom kernel.
