We revisit the issue of gravitational contributions to soft masses in
five-dimensional sequestered models. We point out that, unlike for the case of
F-type supersymmetry breaking, for D-type breaking these effects generically
give positive soft masses squared for the sfermions. This drastically improves
model building. We discuss the phenomenological implications of our result.
