I found out quite a lot of the register set of the DTV bridge (e.g. I2C communication, talking to the tuners and demodulators), but was stuck when it came to DMA transfers (probably because I haven't written a driver for such a complex piece of hardware before). Finally I lost interest because I switched to a PCIe based solution (DVICO DVB-T Dual express, which worked practically "out of the box"). If anybody is interested I am happy to share my notes and the pieces of the driver that I put together.
