Per-Page Styles Method Change

How about adding this to phptemplate_preprocess_page() ?

It adds a link to a stylesheet on a per-page basis if the stylesheet exists.

  // Add page stylesheets.
  if($vars['is_front']) {
    // special style sheet for home page
    $cssFilename = drupal_get_path('theme', $GLOBALS['theme']) . '/css/home-page.css';
  }
  else {
    // all other pages get a style that looks like page-node-1.css or page-node-add.css etc.
    $path = drupal_get_path_alias($_GET['q']);
    $cssFilename = drupal_get_path('theme', $GLOBALS['theme']) . '/css/'.phptemplate_id_safe('page-'. $path) . '.css';
  }
 
  if(file_exists(getcwd() . '/' . $cssFilename)) {
    $vars['styles'] .= '<link type="text/css" rel="stylesheet" media="all" href="'.$cssFilename.'?L" />' . "\n";
  } 

Now all a user would need to do to include a new stylesheet for a page would be to create a new stylesheet with the correct name and it gets automatically included on that page.
