It looks like it is a bug in upower version 0.99. I noticed that upower -d did not show can-suspend or can-hibernate with that version installed, however it showed up with 0.9.23. I downgraded from 0.99 to 0.9.23 and rebooted (with pm-utils installed), and upon reboot the sleep option was available. So, as a workaround, just try downgrading upower from 0.99 to 0.9.23 (then reboot) until the issue is resolved.
