The various GMA500/600 type devices are all pretty similar at the
GTT/memory/PCI layer so the chances are it'll mostly work. How well it
works will depend in detail upon the videout output side of your hardware
platform and how much the E600 differs from Moorestown/Oaktrail. In
particular if you have a MIPI output then it'll need a fair bit of work.
I've not seen any Linux drivers with the non-free userspace for the E600
yet and until those appear there are no kernel bits to work from to drop
into the gma500 driver.
I'd take it up with your board vendor and Intel see what their plans are.
