Page template suggestion per language? How can I add page templates for different Languages in my Drupal 6?

For example, if I want to make different page template for Bulgarian language, page-bg.tpl.php doesn't work.
A drupal.org groups comment shows examples how to allow use of multiple tpl.php file versions.

Using 

&lt;?php $vars['template_file'] ?&gt;


it is possible to create your own template file suggestions. 

Example:

function phptemplate_preprocess_page(&amp;$vars, $hook) {

  if($vars['language']-&gt;language == 'bg') {
    $vars['template_file'] = 'page-bg';
  }
}
