Edit: and I know I'm comparing apples to oranges, since Intel's IGP will never do more than 2D in Linux, while ATI's open source drivers should offer 2D, 3D, possibly hw video decode and a perfect suspend/hibernate experience in the future. It's just that getting updated about suspend/resume advances can be as important as updates on 3D or hw video decode.
I got an Intel based notebook with gl960 (= stripped gm965) and it does 3D. compiz fusion works (albeit xv + compiz fusion does not ...), and I can play quake III at 1280x800 ~40fps. It is too slow for nexuiz, ok,
but it does 3D (if you are not a hardcore gamer)
