Comment (by chmac):

 Ok, the change was merged in from WP 2.3, but the output of $upgrade was
 disabled. I guess that makes sense if update notification is disabled in
 WPMU.

 What about adding a filter to blank it instead? Would make the merge
 easier.

 add_action('update_footer','wpmu_update_footer');
 function wpmu_update_footer() { return (null); }
