omega, that's correct.
At the moment, I have the GPS working (qpeGPS and gpsd)... and I have Kismet working, but for some reason, all versions of Kismet compiled for the Z that I've tried (2.6.0, 2.8.1, 3.0.1, 3.1.0) either don't work period or don't use the gpsd. The *best* one has been 2.8.1 (which is really 2.6.0 according to the ipkg info).
I wrote some diagnostic programs in perl... and found out that even after configuring kismet for gps collection, it only sends a single gpsd request ('PAVM' for Position, Altitude, Velocity, Mode) when you hit Shift+Q to close down kismet.
I was/am planning to "do it myself" but am struggling with getting the cross compiler environment set up on my Debian system. It seems all the instructions / help / howtos out there are geared mostly towards the Red Hat / 5500 combination.
