Tried 2.6.20-13-generic (which has the stop_on_shutdown) on an Acer TravelMate 8101, and it still makes that ugly, loud sound at shutdown. BTW the sound has nothing to do with the little rattle that comes when the disk hasn't been used for a while (for instance after halting in grub), which I though was the "parking" sound. I have tried to record it, but my recording gear is not good enough.
