Using GPS as a reference clock for NTP?

I have a GPS device on my box and would like to use its PPS (I believe
it's the $GPRMC message) as a reference clock for ntpd? I assume it's
possible? Currently, there is no driver for the GPS device, I'm
getting position updates by opening the ttyS0 comm port and reading
$GPGLL messages.

Any ideas?
