Try using the boldmath package. Just write \usepackage{bm} in your preamble, and then, inside your math environment, write \bm{\pi} and you'll get the bold pi character.

This happens on DVI, PS and PDF exports too. Do I have to choose a different font (I use palatino 12pt)? Or maybe a particular Postscript Driver (I'm with default)?
