I think I'm seeing this same problem on a Toshiba Satellite A205-S4577, running the just-released Feisty.
The Intel PRO/Wireless 3945ABG in this laptop is detected during boot, but I get the "Radio Frequence Kill Switch is On" message, and the wireless interface is NOT shown in "ifconfig -a".
Wireless appears to be turned on/off via a hotkey (Function-F8), but this has no effect in Feisty.
