Thanks for bringing this up, indeed there's some cleanup in order

Indeed the maps which don't currently use f22 should be fixed,
regardless of what happens in X/kernel/userspace. My main concern is
that F22 has acted as touchpad toggle key for years (many of those
were imported from hal-info originally), so if we change everything to
f21 now without updating userspace (things like gnome-settings-daemon)
in lockstep, then we break existing functionality.
It would look slightly weird, but perhaps it might be better to keep
using F22 for toggling, and F1->on, F23->off?
