Martin, here are the configuration files I have.  Without these (I 
suspect) PPS wouldn't be available:

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
     /boot/config.txt
.
.
.
# PPS support
dtoverlay=pps-gpio,gpiopin=18
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
      /etc/modules

# /etc/modules: kernel modules to load at boot time.
#
# This file contains the names of kernel modules that should be loaded
# at boot time, one per line. Lines beginning with "#" are ignored.

i2c-dev
pps-gpio
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

gpsd itself works (tested with cgps -s) and ubxtool gives sensible results.
