Basically the instant on feature, is they are running a small arm board piggie backed on the board(actually on some its built right in to the latop's motherboard). When you are not using the laptop or have the laptop in windows mode the board is in deep sleep. It is instant on in the sense that the machine is always technically running. Coming out of sleep, it comes up in a matter of seconds.
The OS is MontaVista Linux. The piggy back board(basically an omap3 from TI iirc) actually only has a few pieces of hardware on it, and uses most of the peripherals on the main laptop connected via an smbus/usb.
