I went for a slightly different (but better solution):

Since PETScPreconditioner and uBlasPreconditioner don't have much in
common, it's not obvious that we should make a typedef Preconditioner
for one of them. They assume different data structures and if someone
wants to make their own preconditioner, they probably need to know the
data structure: PETSc or uBlas.

So I just put the enum list straight into the common file
Preconditioner.h that all can use. This simplifies the usage a bit:

    KrylovSolver solver(amg);

No need for prefixing with some namespace.

Will do the same thing with FooKrylovSolver::Type --> KrylovMethod.
