You know that using buzz words doesn't make it easier to test it.
I know that there are some power levels, but I don't want to spend
hours to find out what it does, after looking for S4BIOS and didn't
easily find it.
And what version of NetBSD does it take to use machdep.sleep_state?
Please provide enough informations to make it easy to test it
if you want some feedback (e.g. the breakpoint and so on).
