So this would mean that one can get the TT of the current channel,
at the rate delivered from that channel (don't know if that would
be any faster than that of analog TV).
I guess it wouldn't buffer _all_ pages and allow instant access,
would it?

A solution I would consider better would be to collect the TT pages
just like the EIT data and have all TT data from all channels
available and display it via the OSD.

Maybe you could make the teletext VBI insertion optional, thus
allowing the OSD to use the memory as it has done up to now?
Just a thought...
