Linux 2.4 with the PPSkit has been around a while, is stable, and works 
quite well with ntp-4.2.4 with out any nmea patch.  That ntp-dev-4.2.5 
does not work suggests that the problems we are having with it and linux 
2.6.31 might be present even if the nmea patch were installed.

I suspect any breakage in the way the development ntpd handles pps would 
mask anything done in the nmea patch.  That is, ntpd itself has broken the 
pps api.

There is a new development ntpd out that I haven't had a chance to test to 
see if problems are still present.

I am curious, though:  where in ntp-dev would you find the "common PPSAPI 
code" that replaces the stuff that used to be in refclock_nmea.c?
