Page template suggestion per language?
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';
  }
}
