The point of my maneuver was to add some extra space around =, so I 
tried \renewcommand*\@aciii{\mathbin{\,=\,}} instead, but got ``missing 
$ inserted''.  Tried your version, same error.

I guess I should stick to my crappy hack, going wth

\let\footnoteclone\footnote
\renewcommand{\footnote}[1]{%
	\footnoteclone{\renewcommand\={\mathbin{\,=\,}}#1}}
