1. You may have a look at the macros module_param and friends.
2. Do you want to read and write files from kernel space (your command
   line arguments imply this)? File access from kernel space is
   (though theoretically possible) a very dangerous thing.
   See the mailing list archives for an explanation why this is
   considered evil. Erik Mouw and others explained that very well.
   (Sorry, dont have a link handy)
3. Your mail client (or you by yourself) did totally mess up your message.
   I see 5 levels of identation here, Please fix this.
