The part I am confused about is how does the kernel ACPI module
map the ACPI hotkey event to the correct device?  For example, if there
is a laptop with a USB connected keyboard in addition to the built in
keyboard.  Is there a way in ACPI to map the hotkey being pressed to the 
logical device or is there an inherent mapping to the "ACPI" keyboard.

Thanks,
