I have never seen this before, but it seems to be a Google Web Search Feature named Q&A. Gary Price SEW blogged about Google Launches Q&A Service, Answers Directly on Results Pages back in April, but the way it is laid out seems different to me then how it was in the past. So I pinged Gary who dug up Philipp Lenssen which proves I am wrong. I figured I share it with you anyway.
A SEW forum thread named "According to" Results in Google discusses the question, on a search ibook g4 memory. So there is the answer, it is not new, its been around since April and is named Q&A.
Update: Note how the link in that result goes to a dead page. Also, Eric Lebeau wrote an entry in French, but I think you can figure it out. Basically it shows how you can use additional operators to get at your specific requested answer quicker and better.
