Alas, it was one of my first attempts; the TV detects something like teletext 
but gives me a "Page not available" message. 
Maybe I'll post this question in the ivtv-mailing-list, to ask them if my TV 
should be able to give me teletext from the VBI-passthrough. I know that 
there's still some development going on there...

As soon as I know more, I'll let you know.

(And if nothing else works, I can always clone my entire X-windows-desktop to 
my TV. It gives me a bit of a nagging feeling though, because the OSD works 
perfectly!)
