Yes, with matplotlib 1.0 bbox_extra_artists now works.
I consider bbox_extra_artists some kind of a hack (IMHO, all artists should be
considered with a 'tight' box), but coming from gnuplot/asymptote maybe my
point of view is biased.
What would be the point of a 'tight' box that excludes parts of the plot? I
would specify the coordinates myself if I needed clipping.

Thanks for the suggestion, that looks promising, but doesn't work:
----
import matplotlib as mpl
mpl.use("Agg")
import matplotlib.figure
fig = mpl.figure.Figure()
fig.set_size_inches((20,20))
plot = fig.add_subplot(111)
plot.set_title("Subtitle")
plot.plot([1,2,3], [3,2,1])
st = fig.suptitle("Horray!", fontsize=20)
fig.savefig("out.png", bbox_inches='tight', bbox_extra_artists=[st])
----
produces:
Traceback (most recent call last):
File "test.py", line 13, in <module>
fig.savefig("out.png", bbox_inches='tight', bbox_extra_artists=[st])
File "/usr/lib/pymodules/python2.6/matplotlib/figure.py", line 1084, in
savefig
self.canvas.print_figure(*args, **kwargs)
AttributeError: 'NoneType' object has no attribute 'print_figure'
I find the documentation a bit scattered around this subject.
I'm not using the pyplot interface, so I guess that .use("Agg") doesn't do
anything for me?
I also have no reason to use the pyplot interface, why should I? I have no
matlab background, and I mostly use matplotlib procedurally (ie not
interactively).
