Interesting, this is card like noone other seen earlier. If there
won't be any other BCM4331 cards available for mini PCIe, it may be
harder to support them. The only solution (except buying MacBook)
seems to be SSH-ing to someone's machine. Or finding a proper adapter
for this kind of slot.

The amount of work mostly depends on used PHY and radio on this card.
This should be possible soon, when bcmai/whatever-name will be ready.
