You can change the page icon itself with a userfunc (the usual overlays 
are still applied). This code was used in a 4.x extension. Use the 
namespaced class names if you make 6.x specific extensions.

Create an extension. In ext_tables.php:

// Defines $icon array()
$pathToExtension = t3lib_extMgm::extRelPath('<<ext_key>>');
$icons = array(
	'mystate' => $pathToExtension . 
'Resources/Public/images/icons/mystateicon.png',
	'mystate_hide' => $pathToExtension . 
'Resources/Public/images/icons/mystateicon_hide.png',
);
// Gives the $icon array to the sprite manager
t3lib_SpriteManager::addSingleIcons($icons, '<<ext_key>>');

// Register userfunc for page icon
$TCA['pages']['ctrl']['typeicon_classes']['userFunc'] = 
'tx_iconClass->getPageIcon';

In class.tx_iconClass.php :

class tx_iconClass {

   /**
    * Determines icon class for special page cases
    *
    * @param array $parameters array with record
    * @param string $ref Unused reference parameters
    * @return string Class name of page
    */
   public function getPageIcon($parameters, $ref) {
     $iconClass = '';
     $row = $parameters['row'];
     if (....some..condition...) {
       $iconClass = 'extensions-<<ext_key>>-mystate';
       if ((int)$row['nav_hide'] === 1) {
         $iconClass .= '_hide';
       }
     }
     return $iconClass;
   }
}

The "hidden" state is a bit special. It doesn't trigger an overlay icon 
to be added to the page icon, but it uses a separate icon.

Your special icons are shown everywhere in the backend where the page 
icon is usually displayed.
