I'll also need to look at how the desktop integrations detect and 
populate the power options that are presented. Right now, at least in my 
desktop environment, only Hibernate, Restart and Shut Down are 
available, but if the S3 option is toggled in BIOS, Suspend is also 
presented, not least since it would appear in hw.acpi.supported_sleep_state.

Going to try this and see what happens.
