Yup. The most frequently useful parts of philosophy of science are sometimes called "formal epistemology," which I picked out as a particularly useful corner of philosophy in my very first post on Less Wrong.

Another example of useful philosophy is a tiny corner of ethics which works on the problem of "moral uncertainty." Proposed solutions in that domain generally aren't developed with AI in mind, but we (at the Singularity Institute) are going to steal them anyway to see whether they help with Friendly AI theory.
