Here's one idea:
------------------------------------------------------------------------
In [1]:fig=figure(frameon=False)
In [2]:ax = fig.add_subplot(111, frameon=False)
In [3]:ax.plot([3,1,4,1,5,9,2])
Out[3]:[<matplotlib.lines.Line2D instance at 0x2c98b70>]
In [4]:show()
In [5]:savefig('foo.pdf')
------------------------------------------------------------------------
And here's another:
------------------------------------------------------------------------
In [20]:fig=figure()
In [21]:fig.figurePatch.set_alpha(0.1)
In [22]:ax=fig.add_subplot(111)
In [23]:ax.axesPatch.set_alpha(0.1)
In [24]:ax.plot([3,1,4,1,5,9,2])
Out[24]:[<matplotlib.lines.Line2D instance at 0x16f7e490>]
In [25]:show()
In [26]:savefig('foo.pdf')
------------------------------------------------------------------------
Does either of these do what you are looking for?

Were the old pdf plots produced with the pdf backend, or with the eps
backend and then converted to pdf with some external utility?
I'm guessing that what happened was that the pdf file didn't specify
any color, and when it was included, it inherited the graphics state
from the including pdf file. I'm not quite sure if that's supposed to
happen when including files, although I can of course see how it could
be considered a useful feature.
Certainly there is no such intended feature in matplotlib. I think I
could support it for monochromatic plots quite easily, but it would be
much trickier if you want part of the plot in the inherited color and
another part in a specified color.
