Looking around the acpi drivers, some hard-encode actions associated to
the events (like brightness control), some emit messages for devd (like
sound control for the asus), and most mix the two options.

Emitting devd events is both easy and highly user configurable. But it
still does not solve the problem of reinjecting the special keys as
generic keyboard events, for instance to let the user configure them
through xorg. Writing a virtual keyboard in each acpi driver seems a lot
of duplication, and maybe too heavy. IMHO acpi drivers should just emit
information to be caught by devd. Maybe with a single format, so that a
shared other component can listen to them and reinject them as generic
keyboard events.
