This depends on the card. I'd start with firmware-b43-installer. IIRC
it will complain if it's the wrong one for the card (but according to
the saucy package it lists the BCM4322 as compatible; not sure if this
is the same family as the BCM43228).

It appears from a quick search that the only Intel-based card that is
included in the whitelist is "60Y3253 - Intel Centrino Advanced-N 6205
802.11a/b/g/n card (Intel 6205 chipset)" [1]. There's a possibility
that there's a hacked BIOS out there which removes the whitelisting,
though (there certainly are for the X61 [2]); I'm not recommending
this but there are threads out there [3].
