I know of two that will work with at least some Aironet cards:

	1) the current Linux 2.4.x "airo.c" driver (by "current" I mean
	   the current kernel version; I don't remember whether support
	   for that first went into 2.4.9 or into an earlier release);

	2) the -stable and -current FreeBSD Aironet drivers (the
	   versions in FreeBSD 4.4 doesn't support monitor mode).

On FreeBSD, you'd use the "ancontrol" utility to put the card into
monitor mode.  I think there's a comand you use on Linux to do the same.

Both of those should work with the current CVS version of libpcap, or
with the 0.7 version.  (On FreeBSD, if you enable "full Aironet header
returned by BPF", it probably won't work, as I think it uses a
link-layer header type not supported by libpcap or Ethereal yet.)
