The kernel has to manage keyboards. There just is no genuine
keyboard device user space could open, nor could we do sysrq
or sak if we left the keyboard fully to user space.

Hence keyboards are a special case unfortunately. We will
have to live with two classes of wakeup, keyboards and power
buttons on the one hand, versus everything else.
