It certainly looks a lot like s2ram to the user. Now, your PC wakes up periodically in s2ram, too; but it is keyboard controller that wakes up, not CPU, so you do not know. On Zaurus, you do not know, either; nothing visible happens and userspace is shielded from these details. Should user really have to know if battery charger is implemented on keyboard controller or on main cpu before he selects which interface to use?
