There is a saa7130 on board which is probably what is allowing me to

when using a few of the different card options (however Ive no idea how 
to tune an analogue card, I'll have to look that up) so it may be 
possible to get the entire analogue shebang working (though I'm not 

The lack of TDA10048 support is disappointing but rather expected. I 
notice there is support for the 10045/6 (tda1004x) and I had a quick
