The code in CVS uses 0x60 for "analogue" and 0x20 for "digital" right now... 
I'll have a look into the finer grained support later.

I've just checked in revised code allowing all the generations of cards to 
cooperate. Can someone check that it still works for the old CA cards please?

The new cards still won't work right - I've not checked in the finalised 
demodulator code. In fact, I believe the current stv0297 code in CVS causes 
an oops right now :(
