Do modern SSD-based MacBook Pro's have an accelerometer / gyroscope / sudden motion sensor?
On my old 2007 MacBook Pro I used to see the Chrome logo shift and tilt on this HTML5 Rocks page, and I'd experimented myself hooking into the
However, neither of these demos work on a 2012 SSD-based MacBook Pro. Additionally

This apple suport page for Sudden Motion Sensor claims all Intel-based Macs have a sudden motion sensor.
So the question is: does my mac have a sudden motion sensor / accelerometer / gyroscope? If so, why can't I see it in
pmset -g output, and how can I make use of it?
Re-reading Apple's support page, I now see this:
Note: Computers with Solid State Drives (SSD) or Flash Storage do not use SMS as the drives have no moving parts.
The question still remains - even if it doesn't use an SMS, does the laptop have an accelerometer / gyroscope?
