John Nelder wrote a paper in the '60's about inverse polynomial regression that
might give you the sort of fit you need.  I can't recall the exact reference,
but it is discussed in McCullagh & Nelder's "Generalized Linear Models".

>What is the transformation that I need to make to have a linear model?

Can't be done.  That's why you need a generalized linear model.
