Taking out all the details in-between it sounds like you pretty much
agree (at least on the big picture). If the code on the hardware is a
small system of its own, then it should be free software, which means
it would run openBIOS.

So you mean that with the Hurd it might be possible to get a trusted
system despite having some unfree components?
