Before you dump your card, check your config.plist and verify that Kernel > Quirks > DisableIoMapper is set to YES

I had the same problem where my wifi and ethernet was out after the switch:

To get your wifi working you need to update to the latest AirportBrcmFixup.kext you also need to view contents of it, goto the Contents/Plugins and remove the AirPortBrcm4360_Injector.kext from it.
