Thanks Paul.

I have successfully created the links as directed.

When I start ntpd, it quickly acquires the network servers I've 
configured but says nothing about 127.127.30.0!

sunblok_# ntpq -p

The relevant portion of /etc/ntp.conf is:
#
# NTP Time Servers
#
# Reference Clock (Motorola Oncore M12)
server 127.127.30.0 prefer
fudge 127.127.30.0 stratum 0
#

and all of /etc/oncore.0
sunblok_# more oncore0
# /etc/oncore0
#
# Reference Clock configuration for Motorola Oncore M12
#
MODE 4                  # Hard reset, do site survey.
LAT 39 45.3802          # Positive is North.
LONG -75 04.273775      # Negative is West
HTGPS 104.5             # Height in feet.

It seems obvious that I'm still missing something.
