Glad it's working.
You *should* now be able to just add the script you want to run to /etc/profile and it should run. That is if you're logging in automatically to a virtual terminal and not using a window manager. Ant's talk of window managers has me confused.
Edit: Although Ant's approach of running it as a daemon will make sure it comes back up if it crashes, which adding it to /etc/profile won't. So it's a better solution.
