I got it working through modifying some previously modified kexts, and I want to share this fix to anyone with this card.
Anyway, here's the guide.
1) Download the zip through the attachment or follow this link: [url="http://"http://www.mediafire.com/download.php?jqz6rhhwj8sf3rr"]Broadcom 4306[/url]
2) Extract and use the kext utility to install the kexts to system/library/extensions.
3) Rebuild caches
4) Add "max_valid_dma_addr=1024" to the boot.plist.
Wifi should work now!
Please post your results!
