I'm now thinking that defaulting to a high latency sleep state would sort of be required by the pm_qos API -- after all if nobody registers a latency requirement then there is no latency requirement! I think we need some GUI though to adjust this -- like the "inhibit screensaver" applet that exists -- so that users of applications that don't register requirements can still do something useful. johannes
