in ipython -pylab, I tried something along the lines of:

from matplotlib import rcParams
# pslatex is my default latex font package
figure()
title(r'hello matplotlib: $x=e^{i\pi\theta}$')
savefig('pslatex.eps')

rcParams['font.latex.package']='type1cm'
figure()
title(r'hello matplotlib: $x=e^{i\pi\theta}$')
savefig('type1cm.eps')


Both of these figures look the same on screen, but type1cm is used in the 
epsfile. Does backend_agg read the rcParams dict during module import only? 
That might explain this behavior...
