That seems right. Unfortunately the naming between the kernel, X.org, and other places is horribly inconsistent. The kernel knows KEY_SUSPEND, which means "hibernate" (suspend to disk), and KEY_SLEEP, which means "suspend to RAM".

I guess the reason for the key not doing anything is that hibernate is disabled by default in Ubuntu. If you want to re-enable it, you can do that in

  sudo gedit /var/lib/polkit-1/localauthority/10-vendor.d/com.ubuntu.desktop.pkla

and remove the "[Disable hibernate by default ...]" block (there is one for upower, and one for logind if you are running Ubuntu saucy already).
