Any chance to wake up from actual Power Off (S4)?

Hi,
my test machine is a Asus K8N-E Deluxe board. I've got wake from Standby (S3) working fine.
For a new machine, I'm looking at possibilities to wake up from actual power off (S4). I'm looking at an Asus A8N-VM CSM board for the new box, and the board manual mentions the possibility that USB device can wake up from S4. However, I like to belive it when I see it -- does anyone have wakeup from power off successfully working?
