IIRC, it's the antenna PLUS the WLan card that gets FCC licensed,
so you violate FCC rules by allowing a card without an antenna,
and this is why even 'regular' pcmcia cards all have their own
'unique' antenna jacks, so you can't plug in an off the shelf antenna
and boost your signal.

So the theory that the IBM laptops with built in antennas can't
use just any mini-PCI card makes sense, even if it is stupid.
They would have been licensed for specific cards only, and would
be violating the FCC license to use other cards.

I hope that's all it is.  If they had some other reason I'd be very
pissed off if I bought a stinkpad.  (Wait a minute, I did buy a
stinkpad :)
