Yes, in this way it don't make much sense and it will not work (e.g. for 
example to which module belongs the callback?). I planned such things for 
an extended module interface. Dynamic unload of modules is a little bit 
problematic as until now no kernel part track a reference if the module is 
still in use (I'm sure a module unload should be denied if some kernel 
data structures still reference it :-)).
