Nothing specific, but perhaps something at http://wirelessdriver.sourceforge.net/ would work for you. If not, contact the folks there. They're happy to hear from anyone with questions and will give you a straight answer, not like the wireless card manufacturers who say, "We're currently evaluating the issue of developing an OS X solution...." B*stards. If I hear that from one more vendor I just might end up in a bell tower somewhere with my rifle.
