I have recently done something like this in one of my own modules:

    if ($node->type == 'page' && function_exists('menu_breadcrumb_init')) {
      // Since menu_breadcrumb does not expose their API, we’ll have to 
      // resort monkeypatching the $conf array before re-running their 
      // init function.
      global $conf;
      $previous_value = variable_get('menu_breadcrumb_determine_menu');

      $conf['menu_breadcrumb_determine_menu'] = 1;
      menu_breadcrumb_init();

      // Revert to the previous value, unsetting if variable_get returned 
      // NULL, meaning there was no previous value.
      if (is_null($previous_value)) {
        unset($conf['menu_breadcrumb_determine_menu']);
      }
      else {
        $conf['menu_breadcrumb_determine_menu'] = $previous_value;
      }
    }

It would be nice if you could disable menu_breadcrumb completely and then only invoke it from your own code, since it might not always be applicable to the whole site.

One problem might be that menu_set_item doesn't work everywhere (hook_init seems to be the only really reliable place). See #520106: Allow setting the active menu trail for dynamically-generated menu paths.
