The GPS parser is pretty simple; are you using gpsd or kismet's serial driver? The speed just comes straight from the GPS.

if gpsd, take a look at a raw dump (I don't use gpsd anymore but I'm sure there's a way to get it), if serial, take a look at the NMEA w/ tmux or minicom or something, and see what's getting reported.
