AFAICT, kismet is of little use on the n8x0 because it doesn't seem to play nice with the cx3110x wireless driver (vice versa, rather). Many surmised this was due to Nokia's connection manager (icd), but having tested it without the connection manager running, I'm relatively confident that the driver just doesn't behave the way kismet expects it to in monitor mode. The situation may improve later since there's a new open source wireless driver being developed.

This info is accurate, from my experience as of chinook. If someone has more recent info, please share.
