Hi All,
I stumbled upon a solution for my problem after Federico pointed me in the right direction by pointing out the amssymb call in todo itself and the fact that it is a font-related package...
I moved
\usepackage{todo}
to the beginning of the preamble.
It seems that under XeTeX/XeLaTeX the amssymb package (or presumably any other package that requires it) needs to come before other packages that use amslatex packages. I am guessing that I was using something else that called an amslatex style package (euler.sty?). I saw references to similar issues arising from the order of package calls under XeTeX in a previous discussion at
http://www.tug.org/pipermail/xetex/2008-October/011031.html
For completeness sake here is the new preamble (that works with the only change being I moved todo up to the beginning):
\documentclass[12pt,letterpaper,article]{memoir}
\usepackage[marginpar]{todo}
\usepackage{ifxetex}
\ifxetex
\usepackage{euler}
\usepackage[cm-default]{fontspec}
\usepackage{xltxtra,xunicode}
\defaultfontfeatures{Mapping=tex-text}
\setromanfont[Mapping=tex-text]{Hoefler Text}
\setsansfont[Scale=MatchLowercase,Mapping=tex-text]{Gill Sans}
\setmonofont[Scale=MatchLowercase]{Andale Mono}
\else
%set the font specifications to use if xetex/xelatex is not available
\fi %closes ifxetex statement
\usepackage{hyperref}
And here is the preamble that was generating the error messages:
\documentclass[12pt,letterpaper,article]{memoir}
\usepackage{ifxetex}
\ifxetex
\usepackage{euler}
\usepackage[cm-default]{fontspec}
\usepackage{xltxtra,xunicode}
\defaultfontfeatures{Mapping=tex-text}
\setromanfont[Mapping=tex-text]{Hoefler Text}
\setsansfont[Scale=MatchLowercase,Mapping=tex-text]{Gill Sans}
\setmonofont[Scale=MatchLowercase]{Andale Mono}
\else
%set the font specifications to use if xetex/xelatex is not available
\fi %closes ifxetex statement
\usepackage[marginpar]{todo}
\usepackage{hyperref}
Thanks,
Rob

I had always just used comments, but the todo package allows me to see a list of my unfinished tasks at the end of the pdf, all in one place. todo has worked flawlessly for me under LaTeX. I really like it.

Has anyone else used this combination of tools? If so, is there a workaround, other than hitting return over and over again to ignore the errors?
