I even started to believe, that this could be a variant having thetda98xx stuff strapped to be hardwired for System-M, hard to believe andI was even involved previously to get something out of them at all ... This could be possible, but it was all bullshit even to think about it. Why that FQ1236A has no support for tda9887 in tuner-types.c ? I don't even ask it the first time ....
