I've actually run into this on several machines that use the BCM4312 Wi-Fi card, a Dell Mini 9, a new Macbook 13" ( 5,1 ), and a recent HP Mini.
I've tried running Hardware Drivers with an Ethernet cable plugged in, and it seems to only detect the card ~ 50% of the time.
I usually end up having to install bcmwl-kernel-source by hand.
Note, my latest testing was done using Karmic Beta UNR over the weekend.
