All the magic is done completely in software, to the point that nVidia boasts how they employ thousands of driver programmers at the moment, so there really is no reason for this technology to miss in Linux, except of course laziness or lack of interest -- or some lame excuse a'la Adobe that the underlying technology does not allow it. It will require cooperation between the Intel driver team and the closed-source team at nVidia though, so politics may become a larger problem than technical issues... And I don't see this ever happening on AMD IGP's for obvious reasons.
It already works in Win7 & MacOSX, so it's not tied to any windows-specific architecture either... so I hope we see this in Linux sometime, preferably soon, since it's a great laptop/netbook technology!
