I discovered that I too had been affected by this bug after a dumb attempt to speed things up a little and removing gnome-power-manager from the list of startup applications. Adding it back to the startup applications and adding it to my current session corrected the issue immediately as well as restored my hiberante and suspend options. I wish I had more to tell you, but it seems that, in my case at least, I created the issue.
