Funnily enough XKB has had a keysym for this for decades but it's not hooked up anywhere due to the way it's pointer keys accessibility feature was implemented. Theory is that most of userspace just needs to patch the various pieces together for the new evdev code + keysym, it's not really any different to handling a volume key (except this one needs to be assignable).
Cheers,
