Subject: how to uninstall the b43 and reinstall


Hi,

a quick question, how to clear the b43?


a detailed background stories as following:


I installed the b43 following the advice given by list,
mainly from
http://linuxwireless.org/en/users/Drivers/b43

it WORKED.

but yesterday I removed the old kernel 3.2-rc6, which is the one b43 worked,
and installed the 3.2 from kernel.org. I guess it's latest, than 3.2-rc6 ?

I don't know how to remove the b43 since the trial of
make uninstall in pathTo/b43-fwcutter-015 not work.

so I just did something like make install again, and then

dmesg showed me:
