Ah, now I understand what you mean.
Looks like we really need the dock driver to sort of like act as a bus.

Not common at all. Given that it wears the electronics a lot, it must be

Check if /etc/init.d/halt is calling halt(8) with the -h flag. If it is,
remove that -h flag. Usually, there is a hddown variable that holds it, you
just need to get rid of it.
I don't know anything about a Sidux, though.
