Are you sure? I just tested Super Smash Bros Brawl with 4.0-7997 and the hybrid wiimote trick is working. The side effect now is hearing the sound both in wiimote (choppy and garbled) and in the system speakers (clean) at the same time (AFAIR that wasn't the case when the feature got implemented). Haven't tried this trick with an extension, though...
