Actually, I supplied that back on the 4th, but here it is again:

init launches it with the following at boot:

gpsd -n /dev/ttyAMA0 /dev/pps0 -F /var/run/gpsd.sock

For runtime debug, I run:

~# gpsd -F /var/run/gpsd.sock -nND 5 /dev/ttyAMA0 /dev/pps0

I get:

crw-rw---- 1 root root 245, 0 Mar  7 08:48 /dev/pps0

Once again, ppstest has no trouble with it.
