I have an oncore??? that I've never tried.

My sources for ntp-dev-4.2.7p401 don't seem to have any code
for oncore.pps.n whilst it is present in 4.2.6p5.

My couple of suggestions are:

(1) symlink from the serial port device to /dev/oncore.pps.n

(2) try the Atom + nmea drivers as alternative

The oncore driver seems to allow a selectable skew so that
several pps devices can run at the same time so you'd lose
that functionality.
