Yes, I think something like that would be a better default value, but
I'd still like to figure out why I cannot actually control this with the
sysfs power/ attributes that are present.  Somehow it seems that this
support is only halfway enabled and while that triggeres the presence of
the control files, the actual handling is not functional yet.
