I suppose you are right. I probably got confused what I tested where. 
I only installed TL2010 pretest last weekend and I was so obsessed
with testing math, that I may not have looked at hypehenation yet.

Sorry, I didn't know I was supposed to use Babel with (Lua|Xe)LaTeX.  
I was under the impression that babel was for old 8-bit TeX engines only 
while polyglossia was required for Unicode TeX engines.

If this is not the case, I could happily switch to Babel just as well.
Any solution that works across formats for (Lua|Xe)LaTeX would be fine.

Yes, I realize using polyglossia with LuaLaTeX was only a quick hack.
Nevertheless, it would certainly benefit from adding \ifluatex / \ifxetex
to make it run with both engines.

I can give it a test tonight.  I don't have my test files at hand right now.
