Result:
  The Wireless key is not working, from the dmesg it complains:

$ sudo showkey -k
kb mode was ?UNKNOWN?
[ if you are trying this under X, it might not work
since the X server is also reading /dev/console ]

press any key (program terminates 10s after last keypress)...
keycode 240 press

Nothing from showkey -s
