If no one sees a kernel problem here, maybe all suggestions that are
userlevel related could be sent to me privately so that I can't be
blamed of flooding the list with unrelated issues. Thank you.

Hmm, my thoughts exactly. However only libraries I have/had there was
Mesa, tcl and zlib and they still are there. Never theless I ran
ldconfig after the incident. And I haven't yet seen any symlinks in
there except maybe in the GNU emacs share directory. Maybe because my
system really isn't from any distribution. I have just used the a and
ap of some ancient slackware and been installing/upgrading everything
manually ever since.

I will recheck but I don't think this is a problem.

Well I yet have to miss anything and everything runs just fine after
the reboot.
