I found that you can at least active the menu by doing the following:
Create the file /etc/polkit-1/localauthority/50-local.d/com.ubuntu.enable-hibernate.pkla
The file must have the following content:
[Re-enable hibernate by default] Identity=unix-user:* Action=org.freedesktop.login1.hibernate ResultActive=yes
This will only help, if you can at least hibernate by using the command sudo pm-hibernate as described above.
