Kismet and FreeBSD

This topic seems to come up from time to time in #kismet on
freenode.net, without really getting anywhere. Basically, there are a
number of people who would like to use Kismet, a wireless network
sniffer (www.kismetwireless.net), under FreeBSD. Currently it works
with the wireless drivers of Linux and OpenBSD.

The Kismet code compiles and runs under FreeBSD, but when actually
trying to gather data, it comes up with a lot of junk from FreeBSD's
wi driver.

dragorn, the author of Kismet, has this to say on the subject:

<dragorn> the problem is that the fbsd drivers a) don't report the
          right link type and b) don't seem to report packets consistently
<dragorn> when in rfmon
<dragorn> I can find all the bits of the beacon frames, I don't think
          i had a dump with many other management frames in it, but the data
          frames appear completely hosed
<dragorn> if they can either fix that, or explain that all the data is
          in there and I'm just not looking in the right place
<dragorn> I'll change kismet if needs be to accomodate their drivers,
          but as they stand now I can't identify the fragments of the packet at
          all
<dragorn> Theres a header on the management frames, that's OK, I can
          ignore that, and theres a hunk of crap in the middle of the frame for
          no good reason, but I can work around that, too
<dragorn> but the data frames are just all shot to hell

Is there anyone out there who is fairly familiar with the wi driver
and willing to hop on IRC to try and get this worked out?
