The original Airport Card will only work with WEP security, even if you can select the WPA or WPA2 in the list on, lets say, tiger, the OS can handle the encryption, but the card can't, the ROM in the card is just to old, i own a iBook G3 indigo with Tiger on it, and it just refuses the WPA2 and WPA secirity, so why you would find these in the security menu of the airport prompt? Well, it turns out that there are some usb wifi dongles around, i beleive the gray D-Link ones, that also work with the airport/wifi dropdown menu next to the clock, but before you do that, you should remove the internal airport card, just to make shure that it isnt going to use the obsolete airport card, and with the usb wifi dongle connected, you can choose a wifi network, and amazingly, it accepts the WPA and WPA2 protocol, and why is that? Because the D-Link wifi dongle, uses appearantly some similar chipset comming from Lucent (wich was the manufacturer of the Airport card) but whit a different bios/rom that accepts these...
