Ok, just to publicly state that the Intel board apparently was not
attaching to core0. I saw the failure and assumed that it was cpu
related and would be the same as the Asus board. Should I still apply
this patch?

Ok, the patch is applied on the Asus board and it now appears to be
working correctly. I've re-enabled powerd now, so we will see how that
goes. When it was only attaching to core0 the board would hang at times
with powerd enabled.
