Just speculating, as I don't know the mechanics of dual-mic noise cancellation, but is it possible that in some Eee PCs the physical location of the microphones is swapped, causing the inverted noise cancellation pattern? If so, could a basic kernel / ALSA update swap the microphones back in software?
