I think Garth is the man to answer this, but I recall he removed that options 
because it became difficult to maintain as the linear solver can be of many 
different types.

The solution, I think, is to create the linear solver before you create the 
NewtonSolver, grab the parameters, create the NewtonSolver, change whatever 
parameters to the LinearSolver you need through the grabed paraemters.
