I'm not sure exactly what you are asking.  Axes and Subplot don't have
a _figurePatch, but they do have an _axesPatch, which as you note you
can turn off by using frameon=False.  If you want to set it's alpha,
do

  ax = subplot(111)
  frame = ax.get_frame()
  frame.set_alpha(0.0)

Is this what you are looking for?
