Ok. I lump Moorestown and Oaktrail together since they have the same
Z6xx series CPU/GPU (GMA600). I still have a working Oaktrail device
so that support should stay in gma500.

Yes these should be Cedarview/Cedartrail. Some of them are 64-bit and
some are 32-bit. I think it came down to if bios enabled it or not.
Cedarview comes with VGA, DVI and eDP/DP. Quite a few Cedarview
devices exist in the wild.

Yes, it would be interesting to know more about Clovertrail. gma500
only supports up to the Cedarview GPUs but Clovertrail might also use
a Cedarview GPU.
