Replacing BCM43xx wireless card with an Atheros chip

My MacBook Pro has a Broadcom BCM43xx wireless card. These cards are known in the open source world for their lack of fully-functional drivers. I am wondering if it would be possible to replace the Broadcom card with something more likely to have working drivers on other operating systems (*BSD, Linux, etc).

What is the likelihood of replacing the Broadcom card with something with an Atheros chipset, and are there any such cards that have drivers for OS X?

Answer this question I have this problem too

Is this a good question?
