I believe there are GMA600 and 3600 bits buried in the packages for
Maemo/Meego/Tizen vaapi code but I've not looked.

The one for the 3D/2D non-free user space driver. I've been working on
Cedartrail primarily at the moment so not had time to dig further into
the video playback logic. I did get the decoder detected and mapped
happily but haven't yet had time to persuade the firmware to upload.
It'll also need the driver extending to support the overlay planes
feature in the DRI/DRM layer.

I don't know for sure.
