During boot, Apache is actually started as root, but immediately drops its 
privs.

All you need is a program to drop privs (from root to required group/user) 
which then exec(2)s the required program/script to actually run.  (Just like 
cron, login, su, etc do?)  Then put this priv dropper into the boot sequence 
where you want the program to start.
