Yes, the UK version of the Hauppauge card (Win/TV) has teletext
instead of intercast (WinCast).  However there is also a PAL B/G
version (for most of W Europe except France I think) that will need to
be distinguished and presumably also has the teletext chip.

Yes, TV stereo over here is NICAM digital stereo, and the card doesn't
support it.

I now have the Temic tuner data sheet.  It says that C2 is always
valid, and one of C0, C4 and C6 depending on the voltage on a certain
pin.  But none of these addresses responded.  If I'm feeling brave
this evening I will try to measure the relevant voltage.

The chips in the tuner are TSA5522T,TDA5737M,TDA9800T.  The other
chips on the card are the BT848 and the teletext chip - I'll mail
that number when I get home.
