A pull request would be welcome. Note that we already have the symlog scale http://matplotlib.org/examples/pylab_examples/symlog_demo.html?highlight=symlog which is essentially a logscale with a linear fraction in the centre. As I understand this it is not quite the same but useful for a different purpose
