I think this is a very neat feature. I would prefer though if it
doesn't use a separate configuration file.
If it is for setting  TIME_TO_HIBERNATE only, I'd rather prefer if it
would use the common mechanism by dropping a file in /etc/pm/config.d.

I also think, that ideally such setting is configured with a GUI in
the desktop session.
Maybe it would make sense to extend DK-power/gnome-power-manager, so
such options can be configured within g-p-m and passed down to
pm-suspend (via a command line switch).

I CCed Richard, as I'm interested what he thinks about that.

Cheers,
Michael
