The earliest hook avialable to you is hook_init. I use it successfully to require auth for specific pages in my cas module. Be careful not to rely on the arg() function. It is not always defined when caching is enabled.

Thanks! Putting both the cache_clear_all() and user_access('', NULL, TRUE) statements in hook_init() totally works! Submitted patch for Drupal core here: http://drupal.org/node/170524 -ron
