There are some concepts of God that view him as a sustainer of existence, i.e., God doesn't do anything because he does everything. The issue of intelligent design wouldn't come up in such systems since they are axiomatic, not empirical. With this kind of concept, saying "God did it" would be wholly redundant and the believer would have no hangups with science, aside perhaps from ethical problems which might arise (cloning humans, genetic manipulation, etc).
