Enlightenment "Power Off" on system menu

[Open Slate]

My Enlightenment system menu has some useful commands disabled. Is
there a way to selectively enable them?

Enabled:
  Lock
  Log Out
  Cancel

Disabled:
  Power Off
  Suspend
  Reboot
  Hibernate

I want to enable Power Off and Reboot. I have never had any luck
getting FreeBSD to suspend, much less hibernate, so I am happy to
leave those disabled. I am trying to use xdm rather than gdm or kdm,
and lacking Power Off and Reboot on the system menu makes these tasks
awkward.
