Comment 14 for bug 640992

In my thinkpad, /lib/udevfindkeyboards shows:

  AT keyboard: input/event3
  module: input/event5

The second one is generated by thinkpad-acpi, which is what we want in this case (Manoj sorry if I gave the wrong instruction :-( ).

It may also worth to look at the value of hotkey_*_mask, the use to these masks seems to be filtering out some hotkeys.
