No, I have a better idea. Remove the files {cz|sk}hyph.tex and replace
them by files with the following contents:

texmf/tex/generic/hyphen/czhyph.tex:

I need not do any changes in the current CSTeX. That is very important for
me. You can use these files immediatelly and you cannot wait to the new
release of the CSTeX.

To Johannes L. Braams: please, adpot these files into Babel package.
I don't know the procedure to install these files in all common TeX
distributions. Moreower this is not my bussiness because this is
a Babel problem.

These files requires the csplain version Feb 2000 or newer, because the
t1code.tex file is inputted and this file occurs in csplain Feb 2000.
The teTeX and TeXlive includes this version of csplain from September
2002.
