it depends on your X11 keymap how input events are translated to X11 key 
events.

From the hardware side it should be possible (I assume some IRQs arrive 
at the host cpu even in sleep mode, is that correct?), but I have no 
idea how/whether this is implemented in the linux kernel -- we would 
definitely need some support in the UHCI/EHCI/OHCI host driver stack.
