Hi, I just bought a airport card from OWC: http://eshop.macsales.com/item/Apple/6615048K/ but didn't realize the small print that states this card cant be used on a 2009 running in 64-bit mode. So now I have an card (didn't install yet) and a 2009 Mac Pro in 64-bit mode. Is there anyway to make this work in 64-bit mode? Thanks. BTW, pardon my noobieness.
