Graphics do not work during and after a standard install of openSUSE 12.3 RC1, KDE 4.10, 32-bit on a Thinkpad T23 with S3 Savage graphics and xf86-video-savage driver version 2.3.6-2.1.1
The first part of the install went normally. When it did the first reboot, it could not start the graphics, so did the rest of the install in the text-based mode. That completed OK, including on-line update to kernel 3.7.7-1.2-default.
With the installation finished, doing a normal boot stopped at the statement "Reached target Graphical Interface". The Xorg.0.log file from the failed boot is attached.
The system would boot into "recovery mode" with decent, but slow, graphics.

There are workarounds by Mark Alford described at http://www.physics.wustl.edu/~alford/thinkpad/T23_F17.html, and by oldcpu described at https://forums.opensuse.org/english/get-technical-help-here/pre-release-beta/483333-score-so-far-t-23-x-31-lenovo-g570-12-3-rc1-2.html#post2528944
Both involve enabling the option "DisableTile".
Both workarounds succeeded in getting my T23 (2647-8MU) to boot normally.
