actually macjack has this capability. but it does not help you, since 
there is no way to open a connection.
there is no way to do this on a airport card.
what can you do:
    -  patch the wireless driver to support mac spoofing. i always 
wanted to do that.
    -  upgrade the firmware of a prism2 card and burn another MAC 
address into it.

what probably wont work:
    -  patching your kernel. ( because the airport driver is not part of 
the kernel and not opensource either )

==> if you have an airport card you are screwed. if you have a prism 
card, there is some work todo.
