Yes, I'm writing up my progress step-by-step mainly for my own benefit 
but it may help others as well.  So far I have got as far as getting NTP 
to see the serial/USB data stream from the GPS, and the next step will 
be to try and get the Kernel responding to a PPS interrupt.  Someone has 
done this already, but for an older version of the kernel to the one I 
have.  My notes are here:


I don't yet know whether the gpsd/kernel-PPS is the correct way to go, 
whether you can even combine those two drivers.
