No idea how hard this would be, or if it's the right way to go, but I'm picturing an ACPI keyboard driver that consumes keyboard events from ACPI and can attach to the keyboard multiplexer device kbdmux(4).    Your ACPI mods for your machine would inject events into it (if it's loaded).  That'd be modular and pretty self-contained and could be extended to support other machines.
