So, while I will eventually write up a tutorial for here and elsewhere, here are the basic steps to getting Natty working on the X220T:
1. Install Natty! You'll want to download the amd64 Desktop installer and put it on a USB stick using unetbootin. I had to use the F12 boot menu to select the USB stick. However, the installer resized my Windows 7 partition perfectly well and Windows still works (following the requisite chkdsk). [If you plan to use VM software like VirtualBox, you will want to enable the CPU extensions in the BIOS.]
2. Download the newest source for xf86-input-wacom-0.11.x and extract it. You can find it by following the instructions in section II.b, at the link below. HOWEVER, before building and installing, you need to (as of 0.11.1 -- 6/21/2011) update a configuration file in the sourcecode.

In the source tree, find the file
Code:
.../conf/50-wacom.conf
and change the line:
Code:
MatchProduct "Wacom|WACOM|Hanwang"
... to read:
Code:
MatchProduct "Wacom|WACOM|ISD-V4|Hanwang"
Then, continue the instructions in Favux' HOWTO for compilation and installation. You should not need to modify any other configuration files. (And I'm sure that this will be fixed in the near future.)
3. There is currently a bug in Unity (again, 6/21/2011) that causes screen display rotation issues. However, if you install the natty-proposed updates to Unity, this is fixed. You can see how to do that by following the directions here: https://wiki.ubuntu.com/Testing/EnableProposed Obviously, this could cause some other unanticipated problems for you, but that's just the cost of being such a pioneer. (I only installed the proposed Unity updates.)
4. Install Magick-Rotation, which senses state change in the LCD hinge and automatically rotates the screen. I set it to rotate to the left (instead of the right) so that the rubberized battery "handle" is on the left side, so that I can use it as a grip while writing. (But I'm a righty, so YMMV.) Make sure you follow the directions, as you'll need to confirm to magick-rotation that you want it to load automatically in the future.
OPTIONAL: Install fingerprint scanner support (requires proprietary library from UPEK)
There is a PPA for fingerprint-gui, a fingerprint scanner supporting the UPEK print scanner in the X220T, available here:
https://launchpad.net/~fingerprint/+...ingerprint-gui
Follow the instructions for installation there. I don't recommend installing from source on 11.04, due to some library issues. Also, there is a bug which throws an error when using sudo in the terminal. It does not seem to cause any real issues though, and will be fixed in the future.
Once these things are installed, your tablet will be working pretty much just as you would expect, including multitouch, pen, (even optional fingerprint scanning!) etc. Pressure sensitivity even works in Gimp (although you have to enable pen input in the Preferences), and I had a relaxing time this morning playing Mahjongg using my fingers. Imagine that.
Two pen input tools I have installed but haven't played with much is gok, the GNOME Onscreen Keyboard, and CellWriter, which is a handwriting recognition/onscreen keyboard tool. So far, I'd recommend CellWriter, but I haven't trained the handwriting tool enough to know how I like it yet.
I'm also planning to do a roundup of note taking tools such as Jarnal, Gournal, Xournal, and NoteLab. Only Xournal is in Ubuntu; Jarnal and NoteLab require Java, and Gournal requires some Perl libraries that are not available in Natty (but you can install manually with a little futzing). So far, Jarnal seems to be the most mature, and it works following installation of the Sun^H^H Oracle JVM (and may work with other JVMs).
Thanks again to Favux and everyone contributing their valuable time and energy to making these deices work -- not to mention answering questions. It's pretty unbelievable that I can put Linux on a brand-new convertible tablet and literally within a week, everything I care about working seems to be working. Kudos!
