That helps, but even the switch does not shutdown a semi-awake WLAN card (it
does not shutdown the MAC processor in the card, just the RF stage if that
much...).

Exactly.  Which WLAN card, btw?  Intel used to ship cards that simply
wouldn't even start the MAC processor without the firmware, so all you had
to do to keep them powered off was not to load up the driver in the first
place.  But maybe this is not true for the ipw39xx and ipw49xx...  or did
you have the modules and firmware loaded?
