  Try \startnathequation ... \stopnathequation instead.  Or patch 
t-nath.tex for the same effect, I have (but this might have side-effects):

\let\nath!startformula\startformula
\let\nath!stopformula\stopformula

\def\startnathequation{%
   \begingroup
     \curr@cr@is@wall@cr
     \nath!startformula
       \startnatheq
         \hbox\bgroup
           \dmathon@
           \wall\mathopen{}%
}

\def\stopnathequation{%
           \return
           \dmathoff@
         \egroup
       \stopnatheq
     \nath!stopformula
   \endgroup
}

\let\startformula\startnathequation
\let\stopformula\stopnathequation
