Installing Verious Versions of the Kernel with Ketchup
Matt Mackall created a nice utility to automatically download various kernel patches and update kernels with his utility ketchup. You can get the original version from http://www.selenic.com/ketchup/.
Steven Rostedt has modified this slightly to be aware of the latest versions of the -rt patch. You can get that from http://people.redhat.com/srostedt/rt/tools/ketchup-0.9.8-rt2.

This automatically downloads and installs the kernel as well as applies the -rt patch. The -r switch renames the current directory to linux-2.6.23.1-rt7. The -G switch is to prevent ketchup from verifying against stored GPG keys (which I didn't have locally).
Ketchup can also be used to update a current directory to a new patch.
