You need the magic "axis alignment" incantation:
\entrymodifiers={+!!<0pt,\the\fontdimen22\textfont2>}
(or, to adjust only the \bigoplus object, use
\begin{equation}
\xymatrix{
0 \ar[r] & *+!!<0pt,\the\fontdimen22\textfont2>{\displaystyle\bigoplus_{x \in X} g_x} \ar[d] \\
& M
}
\end{equation}

Is there an archive for this list? (and if so where? If not, perhaps
the list owning poeple would consider adding the list to gmane.org)
