No, the formats are obviously enabled already; the error is happening  
during creation of the xelatex format, which wouldn't ever be  
attempted if it weren't enabled in fmtutil.cnf.

The errors shown:

look very much like there's a text encoding problem with the Galician  
hyphenation file. My guess is that the Arch Linux package has been  
updated with a newer glhyph.tex than originally shipped with TL2007,  
but the "wrapper" file xu-glhyph.tex that loads it as Unicode for  
xelatex has not been updated to match. That would be a packaging  
error by the maintainers of that distribution, I guess.

Arno, to confirm whether this is the real problem, please show us the  
output of the two commands:

     head /opt/texlive/texmf-dist/tex/generic/xu-hyphen/xu-glhyph.tex
     head /opt/texlive/texmf/tex/generic/hyphen/glhyph.tex

This will show the first few lines of each of these files, so we can  
see from the dates and versions whether they are the correct ones.

A workaround would be to disable the Galician language by commenting  
out the entry in language.dat, or via the "hyphenation" option in  
texconfig (or another configuration tool, if the Arch package is  
different from plain TeXLive). However, it would be good to check  
what's actually wrong, and report it to the package maintainers.
