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%
my 0.02=80
