I just wrote up a simple JavaScript code for the Polish (update, after 30 minutes of writing this email) and English Wikipedia. It changes the title (h1.firstHeading) to the name of the page which is the {{Restrictions}} (or similiar) template.
Just check my JavaScript:
http://en.wikipedia.org/wiki/User:Datrio/monobook.js
And here's an example (after moving the JS to your own monobook.js):
http://en.wikipedia.org/wiki/ITunes_Music_Store
If anyone wants to copy it, feel free to do it.
