That's very strange...

I'm away from my test machine right now, but I'll provide
a diskimage with the v3 patch later, as soon as I can.

I don't think it's related to me using md(4) devices instead
of USB keys, but there's the slight possibility that it may
be the cause (?). I'll also test both v2 and v3 images on a
USB key as well with real hardware to see if it matters.
