Nothing you did _should_ have put the notebook in S1.  acpid had to have
done that. So I still say acpid is processing things in the wrong order.
However, it seems we both may be making an invalid assumption - that is, you
simply can't ever recognize any button push except the power button when you
are in S1.  That's a real bitch...
