Input layer (with the exception of keyboard repeat rate) presently
does not control underlying hardware, this task is left to individual
drivers. For example atkbd is responsible for changing keyboard set,
psmouse is responsible for setting desired report rate and resolution,
control various quirks of IBM trackpoint devices, etc. etc. There are
unlimited number of knobs that may be needed for various devices that
it is impossible to come up with standard interface.

I think enabling/disabling wakeup events belongs with the rest of
knobs in PM (ACPI?) subsystem.
