Reinitialize the keyboard after the ACPI resume event.

Browse Source 
I am not sure if this is absolutely necessary on all systems.  Yet,
there certainly are motherboards and notebook systems which require
this, although there are other systems which just don't.  I hope we
shall know when to do this on which systems, as the development of our
ACPI subsystem progresses...  (I know we didn't need this for the APM
resume.)
