Right, so I ran it on an old dualcore AMD laptop I have lying around here and it didn't show any difference with or without your patch.
For all 4 runs I did with the tool running it without any arguments (so it did the default thing), I got suspend time for CPU1 of 4-6 msec and resume of ~20msec.
I don't know whether it is the dual core or AMD but your patch doesn't change anything on that laptop which is ok, I'd guess.

Yeah, add those numbers to the commit message too.
Thanks.
