Just to spread some KISS :-)
Compiling a debian RT kernel is quite straightforward.

Download debian sources or vanilla ones from kernel.org
Patch according to your release (
http://www.kernel.org/pub/linux/kernel/projects/rt/ )

Run `make oldconfig` inside the sources dir, you will probably be asked
about configs in the newer kernel not found in .config-YOUR_RUNNING_KERNEL

Then follow the common workflow, run `make menuconfig`, at least change
only the PREEMPT opt and seti it to 'complete preemption'.

Create your linux-image debian package with make-kpkg (
http://www.debian.org/releases/stable/i386/ch08s06.html.en)

If your running kernel works this one will too 99.9%
