As my son in law keeps reminding me, "You cannot fix stupid." I'm always 
assuming he is not referring to me! :)

Along a similar vein, the helpers on the openSUSE forums are consistently 
recommending that Broadcom users install wl and blacklist ssb and b43. I have 
given up trying to overcome that issue. I feel that if people fall for such bad 
info, then they deserve to have their wireless fail every time that the kernel 
is updated, and that kernel developers will ignore the oops reports coming from 
their tainted kernels.

You know as much or more than anyone about b43. Please make any cleanups that 
you want on the wiki.
