In most setups (Gnome Shell, Unity, etc) the window manager will
intercept the XF86MonBrightnessDown (etc) keys and perform whatever
action you have mapped to those keys, and no windows will actually
receive the event.

So if your Emacs gets the event, something was misconfigured in your
setup, I think.

Having Emacs bind these keys globally to `ignore' wouldn't be a good
thing, I think, so I'm closing this as a "wontfix".
