First to correct some confusion (and a good candidate to add to the new
docs that everyone is working so hard on...): mathtext and usetex are
completely independent systems, and you can only use either one of the
other. Therefore, if usetex is True, none of the mathtext settings will
have any effect.

This is not something that is directly supported. When usetex is True,
all of the rendering happens with (La)TeX, so you're limited by what
(La)TeX can do. You would probably need to find some LaTeX package that
does this, and then \include it in the LaTeX preamble using the
"text.latex.preamble" setting. My quick Googling didn't reveal anything
that can do that, however.
You can get bold in a math expression by enclosing content in \mathbf{},
but that is by definition "upright" bold. The reason, I believe, is
that (core) LaTeX simply doesn't include the fonts for Greek characters
and other symbols in bold.
Cheers,
Mike
