That would be the code in our subversion repository scripts.sil.org  
(see the XeTeX for Linux page, for example). It's not always as  
stable as the released version (should be), though; depends what sort  
of experimental stuff is going on. I'd recommend the 0.996 release as  
your best option.

In that case, I suspect something is wrong with the hyphenation  
patterns or language configuration or something like that. To look  
into this, it would be helpful to see the .log of your job, as well  
as the .log from the creation of the xelatex.fmt file. However, I  
think trying your file with a standard TL2007 installation is  
probably a better and quicker way forward.
