I'll get back to you on this asap. Up to my elbows in other stuff right now. The quick answer is that you can easily write/modify the /etc/rc.local script (a link to /etc/rc.d/rc.local) as needed for this sort of cruft. This script is run after all the other scripts for your current run level are executed, which btw are found in /etc/rc.d/rc<runlevel>.d - ie, for normal GUI boot, /etc/rc.d/rc5.d where you will find all the startup scripts for the various system services at that run level.
