what makes you think that the Canon system or any other IS system in a modern camera isn't backed by the same set of electronics? the Olympus gyroscopes are much too tiny to control the moving element themselves and feed into an electromechanical system just like the Canon and Minolta ones do. why do you think the Canon system is remarked about as a big power drain when it is enabled? the pendulum in the Canon system is way too small to move any correcting element by itself. what do the electronic mode switches on the Canon IS lenses for different modes of IS otherwise do then?
