Well, I think it would be too much difficult for a user to understand
what happens. For me, a power management policy should be predictable.
For advanced actions, I think the user can manually request what he
wants, for instance:
- going to lunch: press the “suspend” button and pack his laptop;
- going to the conference room: close its laptop (the backlight should
  turn off as there is no need to light the keyboard for nothing);
- making a pause during a conference: press the “blank” button to save
  some power during these 5 minutes.

What happens when someone closes its laptop should depend on what he
expects to see happening (read: configurable):
- nothing (screen blanking, of course, still no need to light the
  keyboard);
- suspending to memory;
- suspending to disk.
But a kind of hybrid behaviour would be, in my opinion, just too
disturbing. One should be able to know in what state he will get his
laptop next time he uses it. :-)

One exception: emergency actions, as running out of battery or
overheating. If I understand correctly, Eee PCs do evacuate heat by the
keyboard, but closing the lid is not enough to overheat them, right?
