Some more data...
If your machine has an old-school AirPort card built in, you may want to disable it. If you don't, the Network Preferences panel may wind up confused. The easiest way I've found is to cd to the Extensions directory, kextunload AppleAirPort.kext, then rename the AppleAirPort.kext and the AppleAirPortFW.kext so that they don't have .kext at the end of their name.
Airport Extreme cards don't seem to be able to connect to FreeBSD machines running 802.11b cards in HostAP mode. Go figure.
If I were you, if you're using the CardBus variants, I wouldn't attempt to power off the card or remove it while the machine is running. I don't think Apple's driver has been set up to deal well with this, given that they didn't consider people using it with hot-swappable hardware. It is safe to sleep your notebook, remove the card, then replace it before you wake. It definately is unsafe to forget to replace it before you wake. What happens is the screen greys out and you get a box telling you in 5 languages that you must power off and restart your system.
