Michael's probably got the best info here. The patch comes from the
Pepper project.

As I understand it, it requires use of a calibration tool, "like
xcalibrate". I've not yet found an appropriate calibration tool to
suggest to testers, but gather there's a few out there - just not in
Ubuntu yet. If you find one you like and let me know, I can work on
incorporating it into Ubuntu.

I've attached it to this email. Also, it's been added to the evdev
driver in Gutsy, so should already be installed for anyone with an up to
date Gutsy.

Yes, the patch should work fine built against the Feisty -evdev.
Some good documentation for creating debs from source packages, with
patches is available at http://doc.ubuntu.com/ubuntu/packagingguide/C/.
If you're interested in learning, this patch would give a good example
to work through.
In case you actually just want the deb, I've gone ahead and built a
Feisty version with this patch for you here:
http://people.ubuntu.com/~bryce/Testing/evdev-Feisty/
I haven't tested this deb out though, but expect it should work about
the same as the current Gutsy version.

P.S., these are the steps I did to build the deb:
1. On packages.ubuntu.com, looked up the Feisty .dsc for -evdev
2. dget -x
http://archive.ubuntu.com/ubuntu/pool/main/x/xserver-xorg-input-evdev/xserver-xorg-input-evdev_1.1.5-0ubuntu2.dsc
3. cd xserver-xorg-input-evdev-1.1.5/
3. Copy the patch into debian/patches/
4. Add the patch name to debian/patches/series
5. dch -i and add a new changelog entry, and set version string to
1.1.5-0ubuntu2~ppa1
6. debuild -sa -S
7. cd ..
8. pbuilder build xserver-xorg-input-evdev_1.1.5-0ubuntu2~ppa1.dsc
