Hi Peter,

I don't think there's any problem with using the amsmath and amssymb  
packages in XeLaTeX. XeTeX is now able to use PFB fonts, and in  
particular the CM and AMS fonts.

The problem you're referring to, I think, is one that occurred when  
attempting to use the AAT text fonts, as allowed by XeLaTeX, in  
maths. This required additional code, such as:

\SetSymbolFont{operators}{bold}  {\encodingdefault}{\familydefault}{b} 
\SetMathAlphabet{\mathrm}{bold}  {\encodingdefault}{\familydefault}{b} 
\SetMathAlphabet{\mathit}{bold}  {\encodingdefault}{\familydefault}{b} 

which could cause problems. Will Robertson has AFAIR dealt with these  
issues in the latest versions of the fontspec package, such that  
there shouldn't be any problem. For example, he introduced a legacy  
math fonts (CMR) to take the math accents from.

A preamble I would suggest is like this:

     \usepackage{color} % for color
     \usepackage{amssymb} % for math symbols
     \usepackage{amsmath} % for math constructs
     \usepackage{fontspec} % for AAT/OT fonts
     \usepackage{xunicode} % for Unicode accents
     \setromanfont[Mapping=tex-text]{Hoefler Text}

With this preamble I XeLaTeX'ed the formula ax^2+bx+c=0 in LaTeXiT  
with no error message (after replacing pdflatex with xelatex in the  
appropriate pref). The only problem is the minuscule size of the  
formula in LaTeXiT's window.

Not sure what you're referring to. But I'm doing so many things at  
the same time now, I don't really remember what I have posted.
