I have heard that at least part of the sidebox is constructed using data from Wikipedia, especially the structured info in the infobox there.

Tom, Google will not tell you. The entirety of how Google search works is a trade secret. We don't know the algorithm for ranking, and we don't know what information they glean from web pages -- and they are unlikely to tell. It is a constant on the schema.org discussion list that developers want to know what Google/Bing/Yahoo/Yandex will do with specific information in the web pages, and it is a constant that the reps there reply: we cannot tell you that. The only way to find out is to code and observe.
