Have you asked Microsoft if they will supply you Linux drivers for the card?

Seriously, there was discussion here a few weeks ago about someone who was using a wired Microsoft NIC, and even though it seemed to be made with a standard chip set, MS had managed to change it enough that it would not work with Linux. And you think you are going to get a Microsoft wireless card working with Linux? I wish you luck, but you are much more optomistic than I.
