[development] altering an altered form

Hi, For the new drupal.hu, I am trying to force the path and node options form groups to be always opened on some node types, and path removed on others. Since the path stuff is added with form_alter, my only way if I understand it correctly is to name my module something post "p", so that it is called after the path module, or manually tinker with the weight of modules in the system table. Am I right, or are there better options? Gabor
