The problem is chicken and egg.  I see how you are doing this now...

detach 0 {
	media-type "802.11";
	action "/etc/pccard_ether $device-name stop"; };

The problem is that by the time the 'detach' comes, the device is no
longer in the system.  It is long gone.  So when we do the comparison
against media type, we have no clue what kind of media it is, and the
test fails.

For now, add a rule matching device name wi.
