I see the logic, but it doesn't seem to have any effect. Does Monobook.php needs to be somehow resourced/refreshed for a change to become active?
It changes the big header on the page. If you also want to change the title (eg. on browser window), change $this->text('title') into str_replace(" ", "_", $this->text('title')) up between the <title> tags.
