Comment 19 for bug 200950

It appears a known issue in the iwl3945 driver, committed patch 3/13/2008 in iwlwifi development.
patch seems potential add candidate for hardy. It does work in my case with Hidden SSID.

Indirect scanning ('iwlist scan') should report information about
hidden APs. When an AP is hidden it does not respond to active scanning,
we thus have to use passive scanning to locate these APs.
