Great.

They even are using the exact same windows-driver ;)

I would like to take care of your patch + I will modify the dib3000-driver 
to be able to set agc-parameters in its config-struct to be able to pass 
the best agc-settings for each of the board.

But before committing I will need your sign-off like:

best regards,
