I do, although I run 4.2.0nb1 from pkgsrc.
$ ntpq -p

Since my kernel was missing the com.c stuff too, I just turned off the
kernel kcbind stuff with this in my /etc/ntp.conf . (It took a lot of
reading the source to ndpd to even realize I could turn that off!)

There were a few hacks I needed to do to get the Motorola Oncore M12
to work. (It appears every oncore type has a slightly different
incompatible command set and the stock commands think they are
initiating a site survey, but the command silently fails and the
oncore just sits there. Using "mode 1" and putting your lat/lon/ht
into the oncore config file side-steps that whole issue.
I too would be thrilled if someone checked in hardpps patches in
kern/13702 (from Aug '2001).
