Kismet as supported IEEE802_11_RADIO for years (as has BSD, that's nothing new)

Make a pcap w/ tcpdump with the linktype set to ieee80211radio and put it somewhere and I'll see if they changed the rtap header.

[edit] Pedro confirms, I'd suggest throwing a debug in on the DLT type to see if Kismet is getting the right DLT at all, and then throwing a debug into the rtap length decode.

[edit 2] Yeah it's not detecting the DLT for radiotap for some reason.

[edit 3] Found it, wasn't setting DLT on packets on BSD at all, checked in possible fix.

[edit 4] Pedro confirmed, this fixes it, grab the svn Kismet trunk, and it'll be in the next release.
