I'm sorry, but I'm not quite sure what you mean by the event number. Is 
this one of the numbers generated by the event?

How do I pass an argument to the method? By the looks of it, when 
undocking the _DCK method should be called, followed by an _EJx method. 
Can I call multiple methods in response to a single event?

It might actually be nice to have an interface that allows userspace to 
call arbitrary ACPI methods at any time, rather than simply in response 
to hotkey events.
