The airo-linux drivers on sourceforge in CVS are broken - the driver locks up when after a few seconds. Unfortunately, these are the drivers for Aironet cards that got put into the Linux 2.4.20 kernel.
The 2.4.19 kernel airo-linux drivers work well and support RFMON - I use these drivers my my Cisco 350 cards.
Alternatively, you can follow the directions from the Wellenreiter project at http://cvs.sourceforge.net/cgi-bin/viewcvs.cgi/*checkout*/wellenreiter/Wellenreiter/docs/README.LINUX.CISCO?rev=HEAD&content-type=text/plain (url *may* wrap :). These instructions are for getting Aironet cards working in RFMON for use in Wellenreiter, and are applicable for generic use.
