The RB has only raw tuner slots with parallel TS data and I2C, the DMA/PCI
stuff sits on the mainboard. In that sense, there's only one DMA "card"
driver, but different tuner drivers depending on the slot ID. I don't have
the Terratec card, so I don't know where the difference in the HW setup is.

Well, it's derived from tda10021, so there's no other possibility anyway...

Ok, then the hard part is already working...

The problems seems to be in the TS interface. There are a few operation
modes, they differ mainly in the way the clock is stretched and/or gated. As
I said, I don't know the requirements of the TS input of the Terratec

The AFC part is different anyway. And if you already have a lock, it's not
anything in the reception itself.

Huh? They are saying that the card manufacturer should break their NDA with
