I'm specifically interested in the Atom N2600 which has a GMA3600 (0x8086:0x0be1 to be exact). I'm also not sure which kernel driver this was developed against. It looks like it might have been against the initial staging variant. At least it still has some references to TTM, so I guess anyone wanting to port it to the new kernel driver would have to convert those to GEM. Do you think that would be doable? Can you say if the GMA3600 is sufficiently similar to make that driver work?
