Just removing your keyboards and leaving the APPLE_INTERNAL_TRACKPAD_KEYBOARD in the xml file I get some funny behavior:

1. I get 2 new sections in the preferences of KeyRemap4MacBook called "Convert Qwerty -> Dvorak on other's people's keyboards" and "Use Dvorak-Qwerty (Cmd) under Dvorak layout on my keyboards (so far so good, apart from: why do you call it once "Convert ..." and the next "Use ..." or does it not do the same thing and I just don't understand what it does?
2. When I set both hooks, the Dvorak layout is deactivated, even so I have Dvorak chosen in the Apple Menu for keyboard input. So, to type in Dvorak I need to decativate "Convert Qwerty-> Dvorak...". But then, with that setting the Cmd-Key conversion does not work.

What am I doing wrong? Do I still need to put in details for my MacBook Pro Keyboard somehow? I am currently not having any external keyboard connected, later in the month when I'm back in the office I also might have to deal with my USB Logitech external keyboard.
