Actually, this isn't true when using xelatex with opentype fonts  
(rather than old-style .tfm files).... because of the different way  
text is handled, you won't see potential hyphenation points in the  
overfull (or underfull) box messages. Similarly, the plain TeX  
\showhyphens macro won't work in this mode.

There was some discussion of this on the mailing list long ago... I  
can't remember offhand whether Will provided a xetex-compatible  
reimplementation of \showhyphens in one of his packages.
