I don't know anything about the IF within the saa7136 -- I would guess it is something like a tda8290 or tda8295, which may need some work for analog support.  For digital tv, you can attach the tda18271 the same way as is done in cx23885-dvb for the hvr1800, with alt_tuner=1.

They should write to the list and contribute, or release facts (not 
conjecture) through a third party.

It would be good to know what devices it isn't working with, and which 
potentially it does. This would help the community refine the driver.
