Changing the functionality of a core role is not something we can really do,
even if that makes sense, for compatibility reasons.

It's actually a really simple plugin.  All you need to do is give Author the
edit_pages capability. Two ways to do it -- alter the role in the database,
or do a filter at runtime. No need to worry about plugin upgrades in that
case, or compatibility with changes to core.

This untested example modifies the roles definition in the DB:

class Nacin_Authors_Draft_Pages {
   function Nacin_Authors_Draft_Pages() {
      register_activation_hook( __FILE__, array( &$this, 'activate' ) );
      register_deactivation_hook( __FILE__, array( &$this, 'deactivate' ) );
   }
   function activate() {
      $role = &get_role( 'author' );
      $role->add_cap( 'edit_pages' );
   }
   function deactivate() {
      $role = &get_role( 'author' );
      $role->remove_cap( 'edit_pages' );
   }
}
new Nacin_Authors_Draft_Pages;
