   Hmm.. and the wireless card always appears on? Assuming the
firmware isn't buggy (did you update it recently? have you booted
other OSes, i.e. Windows or Linux that could be updating the firmware
automatically on load?), it should keep the light for the wireless NIC
properly lit.

    Not in particular (in fact if_bwn has been untouched after
9.0-BETA1 was cut), but as Adrian suggested you should bisect the
source of failure.. it would be a wise idea to load if_bwn as a module
after boot to see if the behavior persists; next I would try out a
revision sometime between r222218 (9.0 Beta1) and your head revision.
Some commits of interest that you might want to try backing out and
testing are:

- 225139
