I'm the one that sold him the card. I've been trying to help snoozy install the card and enjoy every bit of it (as i did with it, which means that the card was and still is working) via PM over Amibay. I suspect that the problem lies in the motherboard revision. it is highly possible that he'll need the PCMCIA reset fix in case he has a moterboard that refuses to collaborate with the card.
So, please inform us about the motherboard revision and we'll see what happens.
I also strongly believe that for the card to be recognized easily he should at least soft kick rom 3.1 or even better buy a pair and install it. I remember that with an A1200 that had rom 3.0, I had to play around a little bit in order for the card to be recognized.
We'll stay in touch m8.
