If there is anything to fix here, it is that we need a suitable signal from the kernel - until then, there will be various user-space mechanisms that all have their own about-to-suspend and resume signals:
* pm-utils scripts get called if you use pm-suspend
* upowers NotifySleep signal is emitted if you use upower to suspend
* loginds PrepareForSleep signal is emitted if you use logind

What has changed in f18 is that GNOME components (gnome-settings-daemon, gnome-shell) are now using logind, because it offers features that we want (inhibitors and delay inhibitors). upower has also been changed to use logind, and NetworkManager is listening for PrepareForSleep.
