Actually, given disk-caches etc. on linux, saving his stuff won't necessarily 
save the users data anyway (in case of power-loss). That means that the main 
sense of that notification is asking the user as fast as possible, and without 
a chance of missing it, whether the computer should _really_ be suspended (or 
shut down).

If the notification is ignored by the user or he doesn't notice it, then he 
will be disturbed 20 seconds later in a much more fatal way. So this 
notification actually _must_ disturb the user, to possibly prevent a more 
significant disturbance.

For sure, the user feels less confused when he's disturbed by a dialog, then 
when he's disturbed by the shutdown of his computer.

I agree that it would probably be better if this was handled somehow 
consistently. But the result would be something similar to a modal dialog 
anyway, as it _must_ disturb the users workflow. Maybe a very prominent 
colored, flashing and non-disappearing popup somewhere near the panel would 
work as well. But dialogs have their advantages too: Everyone notices them, 
and everyone knows how to use them.
