power management/wakeups with qtopia vs 2007.2

[arne anka]

yesterday in installed qtopia to an sd card to check it out, tried the  
phone (worked) and went to bed.
the 2007.2 uses to resume frequently w/o any apparent reason -- as far as  
i can tell the qtopia does not.
yet, it responses to incoming calls and resumes.
in the morning the battery status was better (judging from the battery  
indicator) than w/ 2007.2.
so, what does the qtopia do 2007.2 does not and is it possible to port  
that bit to 2007.2?
