On en.wikipedia, the texvc program has been updated fairly
recently
to include support for both \displaystyle and \textstyle.
If you're
talking about your own wiki, you might consider upgrading
your texvc
to the latest one available. If that's not possible, I
don't think
there is any way to force displaystyle. You *can* force
textstyle
with a nasty hack involving \begin ...
\end, but no
such luck with displaystyle. (Maybe someone else can prove
me wrong.)
