No, this doesn't work and couldn't work. The tarfile contains only _contents_ of the working directory, and perhaps commit-id, but it doesn't contain even shred of history. Git has no information of where this content is in linux kernel git history.

You have to do "git clone --depth=1 <url>"; surrently there is no way to specify "git clone --from=<tag> <url>". I guess you can try to get info browsing gitweb, and fudge with grafts.
