Does the card actually work if you make b43 believe that it has a BCM2063 radio? BTW, all BCM2062 radios seen so far are rev.2, and none have shown this error. Maybe your card actually has a BCM2063 radio, but for some reason b43 detects it as a BCM2062? Also, does the Broadcom hybrid driver handle your card? Thanks, Gábor.
