Yes, I've read the original white papers.

Where does it say anything about 32 bit integers in there?

Point is, even *if* there was some 32 bit value for document ids (dubious) it would take *nothing* to assign a version number to files, update the id to a longer value, and update the SE and crawl programs to recognize the version of the files as they served pages/crawled.
