After staring a bit more at the example configuration file, I can answer
my own question.  This does the trick:

matplotlib.rcParams['mathtext.fontset'] = 'custom'

I'm a bit worried by the note next to this setting in the example
configuration file, though:

# The following settings allow you to select the fonts in math mode.
# They map from a TeX font name to a fontconfig font pattern.
# These settings are only used if mathtext.fontset is 'custom'.
# Note that this "custom" mode is unsupported and may go away in the
# future.

Why is it unsupported?  I find this functionality very neat.

Thanks. Cheers,
Daniele
