This should be all using die notifiers (register_die etc.) like the other kernel debuggers, not own hooks. As you can see there is already a notify_die call around basically all the places you put in a mdb() call, and you can just hook in there. If your other interfaces to the core kernel are clean enough this would even allow to use your debugger as a module.
