Kismet does work well on the n770, but I have had very little luck on the n800. It ends up running, including using GPS if you have a bluetooth device, but times out after a variable amount of time. It just stops receiving packets. I've had it run as long as 30 or 40 minutes, but it's usually 3-10 minutes. This is with the latest firmware.

Also, on the n770 with OS2007HE, Kismet works, but I can't get the bluetooth GPS to run with gpsd. I haven't had time to track down the issue.
