The wp-pear-debug wordpress plugin has been updated based upon  the instructions on the plugin migration page: http://codex.wordpress.org/Migrating_Plugins_and_Themes_to_2.7#Plugins . The plugin now makes use of the register_setting and settings_fields functions on its options page. I have not tested it but it but version 1.4.5+ should work with wordpress MU.

Internationalization support has been added to v1.4.6 with a roughly translated Spanish language file provided.
