qpeGPS (0.9.2.3pre) is working on a Zaurus SL-5500G with the following equipment:
Fortuna Slim Sirf III Bluetooth GPS
Ramco CF Bluetooth
I had to use an older version of gpsd, because the one from the feed isn't working with qpeGPS. Sorry, but I can't find the website any more I got this "gpsd" from.
I did the bluetooth pairing with PID "0000" and edited the rfcomm.conf file so that it looked like (based on the thread "Fortuna Clip-on Bluetooth on Zaurus C760"):
# Automatically bind the device at startup
# Bluetooth address of the device - get from 'hcitool scan'
# RFCOMM channel for the connection
# Description of the connection
comment "Fortuna Slim Sirf GPS";
That was all.
