 I made some changes to the powerhooks to disestablish the interrupt

 1.107 reverted all of the power saving changes introduced in 1.102. I  
 have yet to see this behaviour, but I'll keep an eye open.

 I can see how 1.107 would break suspend/resume, but apart from  
 changes in the powerhook, it should be identical to 1.101.
