We have just completed a new extension for TYPO3.
It displays a message telling the user if the page was not available in the requested language. The message will be in the requested language, and could be placed above untranslated text. There is also support for News and Events (tt_news)

It has all ready been uploaded to the TYPO3 extension repository - AU no translation
