I strongly recommend 3.0 kernel for Intel Sandybridge for various reasons
including a strange lockup bug that was discussed on linux thinkpad
mailing list apparently has been fixed since then.
And then the new Sandybridge Acceleration Architecture which easily
doubles FreeDroid RPG framerate with Full HD display from 30 to 60 fps is
only in 3.0.
