@Adam,

    I used your instructions in comment #15 and although it seemed to
work, but after the restart the wireless would not work. The reason was
that immediately after the restart, before the reboot, the 'wl' driver
was still loaded and continued to provide network access. But after the
restart, when 'wl' was actually not loaded, and the b43 and bcma drivers
were loaded and they did not work.

I am using MacBook Pro 9,1 (bought mid-2012).

I agree with your reasoning that if the in-tree drivers work, there's no
need to fix the bcma/b43 non-free drivers, but as is evident in my case,
the non-free drivers are the only ones that work, and hence the noise
generated by the non-free driver in the syslog needs to be
reduced/eliminated.

SInce these are actually kernel messages, and since kernel keeps a fixed
size ring-buffers for kernel messages, after just a few minutes of
strting the machine, the `dmesg` output has lost all the startup
messages and is filled with these 'Could not get' messages. It even
causes the syslog to cycle files much faster than it would otherwose do,
and hence I lose the ability to go back in syslog history to diagnose
any problems.
