About names, if you are going to implement app-specific icons, I think could be better use "system-shutdown-suspend" and "system-shutdown-hibernate" and activate the GTK+ generic icon fallback[1]. This is really helpful for a11y themes like HighContrast, and save the ugly mix of "normal" icons and HC icons.
Sebastian, icons not includes in fd.o Icon Naming Spec can be added as themable application- specific icons. For details see http:// live.gnome. org/ThemableApp SpecificIcons
