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{matrix} ... \end{matrix}, but no
such luck with displaystyle. (Maybe someone else can prove me wrong.)
