One way is to make sure /etc/rc.local is executable, and put the script 
starter command line(s) in it.  It should then be started just before it 
throws up a login screen. If the script doesn't return, be sure and 
terminate the command line with a &, otherwise you might be hung without 
a login.  Thats called bad form I think.  And you'll have to reboot to 
single user to fix it.
