However, the "model=acer" parameter can be passed on the boot command line to enable such support. Otherwise, it is quite common that the internal microphone does not work. > > > [cut] > > > > Anyway, it's not such quite common that the machine doesn't work > > without the model quirk any longer :) In most cases, we want to avoid > > the model quirk but fixing the pin configuration instead. > > Actually I have to disagree on the "not quite common".

You missed the point. What's not common is that you MUST give the model quirk to resolve the problem. In most cases, it's just a wrongly set pin configuration, or a parser bug. For both of which, the proper solution is not to pass or create a model quirk.
Looking for bugs by google easy. But looking for bug fixes without proper information isn't easy.
