For the archives: I've pushed those patches and a couple of other follow-up ones to the "tablet-support" branch now. While the parts we already have to work well enough, there's still a few bits and bobs that we need to sort out and keeping it on a branch is easier than carrying a huge patchset around. Anyone who wants to give it a try, feel free to to so. We'll keep pushing tablet-related patches to this branch until we're closer to a final product.
