A couple of things:
I was able to install the original xf86-video-intel of OS-12.2 beta-2 back on
my system :), by:
- Mount -o loop /mnt
- Copied from /mnt the
xf86-video-intel-2.19.0_20120601_8eed569-3.2.1.x86_64.rpm to the Cedar system
- On the Cedar system mount on /mnt
- Copied xf86-video-intel-2.19.0_20120601_8eed569-3.2.1.x86_64.rpm to
/mnt/var/tmp
- chroot'ed to /mnt
- removed xf86-video-intel (rpm -e)
- Installed previous xf86-video-intel rpm, using: rpm -Uvh
/var/tmp/xf86-video-intel-2.19.0_20120601_8eed569-3.2.1.x86_64.rpm
Rebooted system all is fine!
My gfx card information is:

I never ever configured the gfxcard manually. At least not that I'm aware of.
I just run the openSUSE installer and after installation, the video is there.
But this does not explain, why it ever worked before. Unless before the update
fbdev X driver was configured manually. But why? And why did this change during
the update?
Fortunately both src.rpms (2.19 and 2.20) are available at:
http://download.opensuse.org/update/12.2/src/
I made a diff between, you can find it attached. It is not just a small patch,
but a rather big file (over 30.000 lines!).
The change notes starts with:
Release 2.12.0 (2012-07-15)
===========================
First the big news, a new acceleration method that aims to be faster and
consume far less CPU than UXA is now available for selection at runtime.
This snazzy new architecture can be selected through use of
Option "AccelMethod" "sna"
in your xorg.conf. Whilst it has been under development for some time, it
has not yet had the same degree of widespread testing of UXA, so tread
lightly. Try it and if you spot anything that can be improved, please do
report a bug.
<<<< >>>>>
Thus it is not a trivial update, but introduces a new feature.
ps: the version number is first line is wrong. It states 2.12.0, it should be
2.20.0
