access control question - 'edit all pages'

I've lost my way somewhere. I wanted to give a certain role permission to update all pages within a certain category, no matter who created them.

I have taxonomy_access for the category part... but it looked like I needed an 'edit all pages' permission first.

So I decided to try my very first patch...

 }

     if (user_access('edit own pages') && ($user->uid == $node->uid)) {
       return TRUE;
     }

So, I do get the 'edit all pages' permission - but the results are not what I expected. The role I gave 'edit all pages' permission to is able to edit pages created by the super-user, but not pages created by other roles.

Been going around in circles, not sure what I've missed.

Thanks...
