Description of problem: pm-suspend and pm-hibernate should print an error message when /sys/power/disk or /sys/power/state are not found but needed, e.g. "Error: you need /sys/power/disk to use pm-hibernate"
Related to #214407 i'll be doing something a little better. In case of suspend we only really need /sys/power/state, only for hibernate do we need also /sys/power/disk so i'll move those checks to the appropriate places and print out an error when they don't exist. Read ya, Phil
