Have you looked at the KXStudio repos? They have a rt kernel that I have
used successfully with Ubuntu 12.04 and 13.04 and it's really simple to
install. They are currently moving from Ubuntu to Debian repos so their
how-to in http://kxstudio.sourceforge.net/Repositories is broken, just look
at these repos: https://launchpad.net/~kxstudio-team/+archive/kernel/
