Simple hack is to edit less /etc/init.d/ntpd
Be sure and save the edited verion as an OS upgrades might over right it.
How to automatically find the GPS after it is plugged in. Read
the port. You should see a NMEA sentence on it. Takes a bit of
shell or perl script.
But a "real" ntp server would have a serial RS232 port and you almost
never re-boot except to replace failed hardware.
