Actually, it looks like the wireless driver has been updated in release 4 of OS 2007 for the N800. I have been able to successfully run kismet now for long periods of time. It still seems to do the "saving data files" thing after a while if you don't interact with it, but it no longer stops collecting packets within a few seconds like it did with release 3. One annoyance though, on at least one occasion exiting kismet has left the wireless adapter in a real bad state. There has always been a problem with needing to reboot to get the N800's wireless working properly again, but I have found it necessary to actually pull the battery to get it working properly again now.
