got it...

#! /bin/ash
hciconfig hci0 up
hcitool cc <your:bt:gps:id:here>
gpsd hci0
kismet
kill `ps -ef |grep gpsd |grep -v grep |awk '{print $1}'`
hciconfig hci0 down

what this will allow you to do is run kismet in GPS tracking mode, and attach maemo-mapper to /dev/rfcomm0 concurrently for that true war-driving experience.

edit1 - what would be really cool is if there was a way to plot APs found as POI's in MM as they were discovered by kismet. hmmm... script fu calls...

edit2 - added a few lines to bring down gpsd and turn off the bluetooth adapter, as well as specify the shell to use.
