Hmm, did you get reports or checked that it actually hangs?

As far as I remember last time I ran a kernel without Peter's power
sequence library on this board it only wasn't able to communicate with
the on-board USB hub (and devices behind it), but besides this was
able to boot successfully.
But my memory may be wrong since it was some time ago.
