The script for above:  I wish there was a way to download older kernel
source if you aren't running the newest kernel. (Anyone know)

--snip shell script--
#!/bin/bash

##
## Download source for kernel
##
up2date-nox --get-source kernel

##
## Install kernel source
##
rpm -ivh /var/spool/up2date/kernel-`uname -r`.src.rpm

##
## Unpack the source
##
rpmbuild -bp --target=i686 /usr/src/redhat/SPECS/kernel-2.6.spec

##
## Create the config file for the kernel (single proc)
##
cp

cd /usr/src/redhat/BUILD/kernel-2.6.9/linux-2.6.9/
make oldconfig

## Make the make file for the firewire modules and run make
