You could write to null pointers.  The last hooks passed to the
grub_register_variable_hook function are the once used.

You just need one hook, that's for TERM.  I think it is safe to assume
that the terminfo stuff is the only user.  When registering you should
get the hook, when you unregister you should remove the hook
(otherwise it can point to a non-existing function).
