It's impossible to override this function.
Why? Look at the functions name. It confusses drupal thinking its an implementation of hook_theme(). So any override in template.php using phptemplate_tiny_mce() or theme_name_tinymce_theme() wont work.
You need to patch the module.
If you want to add a text area that doesnt need tinymce just add an other rule shown by the id of 'my-textarea'.<?php?>
