Jumping through hooks is harder than through hoops, but may be necessary.
config_intrhook_establish() is part of Justin Gibbs' solution for the
problem that interrupts might not work at config time.  Even clock
interrupts might not work at config time, so device drivers shouldn't
call timeout() at config time.
