I'm not sure what you mean here, if you are loading fonts by file name,
then type it all lower case, if you are loading it by font name then the
actual name of the file doesn't matter.

I've a copy of that file that I used for testing while ago, there are
still some withstanding issues, mainly XeTeX limitations (like
extensible arrows), I'm waiting for proper LuaTeX support in
unicode-math (that is why I did all my testing on ConTeXt).

If you have FontForge, you can open the pdf file in it and see what
CMSY10 glyphs are used, and report it to Will.

or use xunicode etc.

A user guide is must for the non-bata release for sure, any one is
welcomed to contribute one, too.
