I'm testing VoodooPS2Controller on a Dell Mini 9.
Keyboard and trackpad are working fine, multifingerscroll, scrollzones, two finger click... but as soon as synapticsconfigload is started the trackpad stops working. I've disabled the LaunchAgent so at least the trackpad works but this way I can't change any settings.
Another issue I've discovered from time to time is that after wake from sleep I have a stuck key with a repeating sound like pressing and holding backspace in a terminal. After pressing any key it goes away.
