Not really. Technically speaking the evdev cam be compiled as a module and it will not be bound to the input device until later. Input devices should be ignorant of the input handlers bound to them, they should just supply event stream and not care about anything else. Also evdev internal structure is exactly that - internal - and the rest of the kernel should not try to poke into it.
