In terms of how to fix this problem, the easiest is simply to ensure  
that amsmath is loaded first and your definition is \AtBeginDocument:

\@ifpackageloaded{amsmath}{%
   \AtBeginDocument{\XeTeXmathcode`\-="2 \symMRM "2212}%
}{%
   \AtBeginDocument{%
     \@ifpackageloaded{amsmath}{%
       \PackageError{fontspec}{%
         Please load amsmath before fontspec%
       }{Bad things happen when amsmath changes things behind my back.}%
     }}%
}{}


However, if you're willing to break out memoir's "\AtEndPackage" code  
(which IMO should have it's own package), you could write instead  
(untested)

\def\define at mathminus{%
   \AtBeginDocument{\XeTeXmathcode`\-="2 \symMRM "2212}}

\@ifpackageloaded{amsmath}{\define at mathminus}{%
   \AtEndPackage{amsmath}{\define at mathminus}}

This would be a little bit more friendly :)

Hope this helps,
Will
