I'm afraid other SuSE versions are also affected.

Below is an extras from an email sent to suse-kde@suse.com on 26 Feb 2006 10:31:14 -0000

After latest update from supplementary source I could not boot into
runlevel 5 on my 10.0 desktop. It hanged when running
/etc/init.d/earlykdm. The workaround was to use earlykdm script from
3.4.2-26 package.
What supplementary information do I have to provide?

Following is the diff between 3.4.2 and 3.5.1-27 versions of
/etc/init.d/earlykdm:
