Ok, found one! In the Mid 09 MBP is a Broadcom BCM94322 Chip. Like on this board : http://cgi.ebay.com/HP-Broadcom-BCM9...-/320520045587 With this chip u will also have 5.0 ghz Wifi... awesome

U need a MiniPCI-PCI Card also.

This SHOULD work! Maybe (!!) u will have problems with the Device ID. I cant say that. When there have a different Device ID u must put your ID in the Broadcom Kext. But i dont think this will be necessary.

Ps: Sorry, my english is not that good
