Regulatory compliance certification is done with unit testing (wireless
card + pigtails + antennae). Allowing arbitrary combinations can
theoretically leave the laptop vendor open to heavy fines; hence some
vendors have taken to disabling a laptop booted with a wireless card
that's not been certified (the bios checks the pci device id and will
not allow the machine to boot if the card isn't on it's approved list).
In practice this bios locking is simple to workaround for cards that get
their pci device id from eeprom--if you're so inclined. A bit of
searching will find articles by people that have done it.

I've seen bios locking done by ibm and hp.  Wouldn't be surprised if
many others do it.
