Weird... It's difficult to tell what you're saying. It's possible that multiple cards would work in some combinations, and just that the ones I tried did not. Also, you're talking about two systems, a laptop and a desktop. So it would be good to get some specifics, like laptop brand and model, whether the desktop dual-card setup worked with FreeBSD (and which version of FreeBSD).
