The classical probe dynamics of the 11-dimensional massless superparticles in the background geometry produced by (Formula presented) source (Formula presented)-momenta is investigated in the framework of (Formula presented)-sector DLCQ supergravity. We expand the probe action up to two fermion terms and find that the fermionic contributions are the spin-orbit couplings, which precisely agree with the matrix theory calculations. We comment on the lack of nonperturbative corrections in the one-loop matrix quantum mechanics effective action and its compatibility with the supergravity analysis.
