Thanks!  I know that you said it was easy, which is why I went the 
OpenBSD route - didn't know it would be that easy though.

So, just to confirm, I need to change the rc.conf line to this, based on 
  the GPS being connected to the first serial port, with PPS on the 
carrier detect pin:

nmeaattach_flags="-t dcd /dev/cua00"

Cheers
