When I fitted an Airport Extreme card (unsure f it was an A1026 or A1027 card) in my PowerMac G5 (A1047/2061) a week or 2 ago, and initially switched on it was not found by Mac OSX system, but after I took the card out, and cleaned it (the gold-finger contacts) and when I pressed the card firmly back into its slot, the following time it was found by the Mac OSX system.
I'm not saying your problem is the same, but it just might be a simple thing like a bad 'gold-finger' contact, after all these cards are not new anymore.
