I didn't do anything but "slackpkg install". Didn't delete/modify any fonts manualy in /usr/share/fonts. What I actualy did was:
1. Installed slackware 11.0 from its CD (Didn't had 12.0

) Installed only base system from a, ap, d, l, n, y series.
2. Downloaded the latest stable kernel source from official slackware mirror.
3. Compiled kernel and installed it, upgrading from 2.4 series to 2.6.
4. Upgraded glibc, glibc-i18n so on and coreutils.
5. Downloaded slackpkg, updated it
6. Upgraded all my system to slackware-current.
7. Installed some base X packages. Found out that "cursor" font was not found. Uncommented FONTPATH's in xorg.conf. Found out that "fixed" font was not found. Went angry >:O
