THis board uses a different channel decoder. Unfortunately, we can't copy
this mechanism directly.

The module tda9887 no longer exists, it has been merged with tuner.
But regarding the diodes: This is why i asked you to do the experiments
with the tda9887 port setting. I hoped that this controls some transmission
gates. BTW: did you try to reload the modules ans i asked you?
