Hi David thanks for the note!  Yeah there are some great ways to push WWVB 
data into ntpd, but the one driver in particular that I was using (or 
trying to use) is a driver actually meant for audio demodulation:

http://www.eecis.udel.edu/~mills/ntp/html/driver36.html

I've been looking at the more recent ntpd code (4.1.73/74) and it looks 
like its audio infrastructure is slighlty more compatible with NetBSD but 
still won't work out of the box.

I'll report back here if I make any real progress.
