I just found XTestFakeKeyEvent, it should work, so another solution
may be a daemon that grabs Aux and Power buttons, handle them and
injects key events.
The daemon may ask the WM for the active window, retrieve it's
displayed name and differentiate key injection according to a
configuration file.

Theodoros has no time actually, but he's interested in such
improvements and promised to give a try in few weeks.
