Forgive me if this is OT, but I have my device set up to softpower and go offline on a power doubleclick. I was able to get this working by editing the /etc/mce/mce.ini file. Specifically the PowerKeyDoubleAction=softpoweroff and ConnectivityPolicyBattery=forceoffline keys. I have sliderotate installed and I noticed that the script made changes to this file to enable the rotating. (Which I didn't want) I'm not sure if the file existed before I installed sliderotate however. Hope this was usefull.
