OK, so I've successfully compiled both and using
latest v4l-dvb sources.  Runs fine with older cards (Nova-S and
Nova-SE), but I'm having problems with my TT S-1401.

The card is recognised when the budget module loads up, but I'm getting
a 'No tda826x found!' from frontend_init().

A snippet of dmesg:

The frontend does get registered and I can run dvbtune against it but it
just sits there polling.

I tried re-loading the tda10086 and tda826x modules with debugging on
but didn't see anything extra.

I'm assuming I'm not missing something stupid like firmware (I didn't
see any mention of it anywhere in the code).

Do I perhaps need a later kernel version?
