At this point I can reinstall the renamed packages. Feel free to check out:
https://launchpad.net/~ubuntu-x-swat/+archive/q-lts-backport/+packages

It was generated with the scripts I uploaded to xorg-pkg-tools:
 - xorg-lts-backport-quantal is special and generated with lts-xorg-rename
 - The rest is generated with lts-stack. I had to add an extra string to the version for testing
   so I could upload after making some fixes.

It seems to install on the precise livecd, although you have to run updates first with my ppa enabled.

I had to make the following changes:
- xorg had to be rebuilt for xserver-xorg-core and xfonts-base versioned depends. I didn't know
  how important they were so I just rebuilt them with an or depends on the renamed versions. I
  also had to remove version from xkb-data, which was the most important breakage it seems.
- rebuilt plymouth to drop versioned depends on libdrm1
- libxklavier rebuilt to drop versioned depends on xkb-data
- intel-gpu-tools rebuilt to versioned depends on libdrm2 and libdrm-intel1

Still broken:
/usr/share/bug. Do the files have to be renamed or not? Currently I am renaming everything,
but I have no clue what I'm supposed to do with this directory.

Different from the rest:
xorg-lts-backport-quantal
- This package I imagined as augmenting instead of replacing, since it has the
  xserver-xorg-input-all and xserver-xorg-video-all packages with renames.
  So my version is just installing xserver-xorg-lts-backport-quantal would be
  enough to upgrade. Not there yet, binary drivers + no hard dependency on -all
  make it fail.

Test procedure:
I booted off the 12.04 i386 cd, then did roughly this:

$ sudo sed -e 's/http/s/.*/#&/' -i /etc/apt/sources.list # Remove http entries to limit upgrade
$ sudo add-apt-repository ppa:ubuntu-x-swat/q-lts-backport
$ sudo apt-get update
$ sudo apt-get dist-upgrade # Pull in updated packages that would otherwise break

$ sudo apt-get install xserver-xorg-lts-backport-quantal \
  xserver-xorg-input-all xserver-xorg-video-lts-backport-quantal \
  libgl1-mesa-dri-lts-backport-quantal libgl1-mesa-glx-lts-backport-quantal \
  # And upgrade our stack to precise!

$ sudo restart lightdm # Magic!

If everything goes well, only renamed packages will be removed.
xserver-xorg-{,video-all-,input-all-}lts-backport-quantal can be
removed at this point, since they fulfilled their purpose of
pulling in the upgraded stack.

Did I miss any package, or can this test be considered 'DONE' now?
