it is slightly more subtle than that (the HTML report shows that better 
visually);
PowerTOP shows 100% only for those devices that claim to support runtime 
PM, but then are 100% busy
(either because the user hasn't enabled runtime PM for the device, or 
the driver is such that it's 100% busy)

devices that do not support runtime PM at all will not show up (but show 
up in the HTML report in their separate section)
