I have the same problem with a Dell Latitude D600, bcm4306 card. After fixing the problem in bug 197819 (https://bugs.launchpad.net/ubuntu/+source/b43-fwcutter/+bug/197819) the wireless allowed me to connect to my network, but after providing the network key it just hangs. I have attached a section of my daemon.log, which seems to contain relevant information.
