Bluetooth turned on?

["Steven M. Bellovin" <smb%cs.columbia.edu@localhost>]

The Bluetooth light is glowing on my laptop, which I assume means that
the device is enabled and hence using power.  How can I disable and/or
prevent that?  All of the bt variables default to "NO"
in /etc/defaults/rc.conf, and I don't change any of them in rc.conf.
Running 'btconfig ubt0 down' doesn't turn off the light.  This is
4.99.49/amd64 from Monday.
