As reported upstream : https://bugzilla.kernel.org/show_bug.cgi?id=42867 we have a kernel lock on Broadcom 4312 hardware if no firmware files are found.
Installing b43-openfwwf worksaround the problem for me.

Kernel 3.3-rc6 solved this bug for me.
Regression : b43 kernel module locks system at modprobe is no firmware is found =>
Regression : b43 kernel module locks system at modprobe if no firmware is found
Seems I tested it badly. I could try the LiveCD Beta3, and the bug is still there.
As we have an open-source firmware available, the solution could be to include it in the Live CDs : b43-openfwwf should be required by all the kernels...
I commited something to meta-task that I hope will ensure b43-openfwwf is always installed : not only this worksaround this bug, but will also allow direct wifi use on LiveCD.
