I've uploaded my traces to

  http://therning.org/magnus_files/b43-trace.txt.xz
  http://therning.org/magnus_files/wl-trace.txt.xz

Enjoy!

I should probably mention that I've upgraded my kernel to

  % uname -a
  Linux ohann 2.6.34-ARCH #1 SMP PREEMPT Sat Jun 19 00:07:49 CEST 2010
x86_64 Intel(R) Core(TM) i5 CPU M 430 @ 2.27GHz GenuineIntel GNU/Linux

It does seem to make a difference to the behaviour of the b43 module.  I no
longer get the repeated failed attempts to re-connect with the AP.  Instead NM
is telling me I have a steady connection, but no data is transferred.
