And now it gets even more fun... after running with the GPS18LVC and
the NMEA driver for a while, here is what I got:

dex ~ # cat /sys/class/pps/pps0/assert; cat /sys/class/pps/pps0/clear
1261210993.678107382#710
1261213720.842435221#3437

I did have flag2 set to 1 for a while as I could not tell if there was
inversion on the PPS signal, but I am not sure if this might be reason
for the assert being stuck now.

One thing is for sure, LinuxPPS still has way too many mysteries for me... :-(

Ciao, Luca
