I took a look and here are some notes:
- it would make sense to update the list of patterns in that file (TeX
Live 2008 will ship with other files than the ones you lists as
examples in hyphen.lan)
- the file is probably only useful for plain (not for XeTeX at all),
in that case, you can load the pattern unconditionally

I guess that these lines:

\begingroup          \language=\czech
\csaccents
\message{Loading Czech patterns in ISO-8859-2 encoding,
         \string\language=\the\language.}
\let\global=\relax
\input czhyphen.tex \relax
\input czhyphen.ex \relax
\endgroup

could be replaced with something similar to:

\begingroup          \language=\czech
\message{Loading Czech patterns in ISO-8859-2 encoding,
         \string\language=\the\language.}
\let\global=\relax
\input conv-utf8-il2 \relax
\input hyph-cs.tex \relax
\endgroup

and this

\begingroup
\input t1code        \language=\toneczech
\csaccents
\message{Loading Czech patterns in Cork encoding,
         \string\language=\the\language.}
\let\global=\relax
\input czhyphen.tex \relax
\input czhyphen.ex \relax
\endgroup

with something similar to

\begingroup
\language=\toneczech
\message{Loading Czech patterns in Cork encoding,
         \string\language=\the\language.}
\let\global=\relax
\input conv-utf8-ec \relax
\input hyph-cs.tex \relax
\endgroup


What do you think?

Thanks a lot,
