[..cbb is dead..]Do you have any other cards to try? All I ever used with NetBSD were wifi cards.That's my only card, unfortunately. I will ask if somebody else got another card and report back.
I have macppc (5.1_RC4) installed on a PowerMac G4 with a cbb slot. I'll be happy to try out a handful of different cards (10 Mbps and 10/100 Mbps PCMCIA are what I have, plus one Cisco Aironet wireless).
