Thanks that you kept me up to date.
I could talk to the developers of the windows driver today:
They told me that indeed the LNB supply chip is behind the i2c gate
of the tda10086 and that it should have the address 0x09 (7bit).

On the MD8800, it is only visible on the first instance, the second
controls the LNB via a GPIO.

Sounds like we will have some fun with these cards....

Best regards
