Comment (by athrxx):

 I have just quickly tested with Dreamm. Weirdly, sometimes the door opens
 with two clicks and sometimes with just one. So I assume that the original
 driver indeed reads some random value from memory (at would-be table
 offset 255) and that value isn't even constant. The door closing sound is
 inconsistent, too.
