I was curious whether this also happens with Dell Vostro 3550 and seems not:

# rfkill list

Now, after doing once Fn+F2 to disable the device(s):

# rfkill list
0: dell-wifi: Wireless LAN
Soft blocked: yes
Hard blocked: yes
1: dell-bluetooth: Bluetooth
Soft blocked: yes
Hard blocked: yes
2: phy0: Wireless LAN
Soft blocked: no
Hard blocked: yes
#

Another press of Fn+F2 enables both at once:

# rfkill list
0: dell-wifi: Wireless LAN
Soft blocked: no
Hard blocked: no
1: dell-bluetooth: Bluetooth
Soft blocked: no
Hard blocked: no
2: phy0: Wireless LAN
Soft blocked: no
Hard blocked: no
4: hci0: Bluetooth
Soft blocked: no
Hard blocked: no
#

BIOS A09 here, linux-3.4-rc7.


Just do not know why I still get those "Unknown key pressed" messages:

[ 2652.048353] atkbd serio0: Unknown key pressed (translated set 2, code 0x88 on isa0060/serio0).
[ 2652.048363] atkbd serio0: Use 'setkeycodes e008 <keycode>' to make it known.
[ 2652.103556] iwlwifi 0000:09:00.0: RF_KILL bit toggled to disable radio.
...cut...
[ 3249.854374] atkbd serio0: Unknown key pressed (translated set 2, code 0x88 on isa0060/serio0).
[ 3249.854385] atkbd serio0: Use 'setkeycodes e008 <keycode>' to make it known.
[ 3250.030173] iwlwifi 0000:09:00.0: RF_KILL bit toggled to enable radio.
