What needs to be done to teach devicekit-power and gnome-power-manager about hybrid suspend?  I am going to have a hybrid suspend mode as an option in pm-utils that does not rely on userspace suspend or tuxonice, but I am not offered hybrid suspend as an option in the GUI.

Right, you have to bear in mind the options g-p-m gives are the ones users understand.

To a user:

suspend = quick, but bad if my battery runs out hibernate = sloooow, but good if my battery runs out

So, to a user, a hybrid suspend is a lot like a "hibernate", except it comes back faster if the battery doesn't run out.

So in that sense, I would think mapping the DeviceKit-power Hibernate() method [and thus g-p-m] to hybrid suspend on systems that support it to be a very good idea.

Of course, that assumes hybrid suspend works as well as hibernate, which may be true or false.

Richard.
