Something that works 90% would be much better than something that
never works... But I don't fully understand what determines, if it
works or not. I am pretty sure that in the past I could use
dbus-monitor on my laptop to detect suspend/resume cycles.

In the meantime I definitely updated the kernel (currently have 3.5.7),
and probably also several low-level user-space tools. But I have no 
idea
what was the factor that made the UPower signals disappear.

Cheers,
    Peter.
