Public bug reported:
On my laptop, a Lenovo T61p I have two radio killswitches. One at the
front, to be considered as a hardware switch and a soft-key (Fn+F5). The
one at the front will disable all radio devices (BT, WLAN and WWAN if
available) and the soft-key will toggle between the different modes
(BT+WLAN, only BT, only WLAN, all off). At least, this was how it was in
Hardy.
Now in Intrepid the situation is as follows.
The hardware radio killswitch at the front will correctly disable all wireless
devices present. When turning it back off (wireless enabled) only Bluetooth
comes up. The event isn't even recognized. (see below)

Clearly, I miss a line like 'iwl3945: Radio Frequency Kill Switch is
Off'. I need to do a modprobe -r iwl3945 && modprobe iwl3945 to make
wireless work again.
Now, for the software killswitch: it doesn't even control the WLAN
module, only toggling the bluetooth state. This is inconsistent with
behaviour in Windows, Hardy and the Owner's Manual. It should toggle
between the states as described earlier.
The model of the laptop is T61p 6457, a 15.4" WUXGA display with NVidia
Quadro FX 570M and Intel PRO/Wireless 3945 WLAN.
