OK, after pondering for a while I think I finally understand what you 
mean: you have compiled xetex from the svn server. At the end of the 
process the xelatex format was rebuilt, using hyphen.cfg from  
polyglossia instead of hyphen.cfg from babel. And this apparently made 
xelatex no longer compatible with babel (well, I thought it would still 
be!). Since this seems to cause problems, I am going to rename 
polyglossia's hyphen.cfg into hyphen_cfg, so that the xelatex format 
will continue to use babel's hyphen.cfg by default. This should be 
better for the time being, since polyglossia.sty is also compatible with 
babel's hyphen.cfg.
