A semiclassical model is used to investigate oscillations of atomic fermions in a combined magnetic trap and one-dimensional optical lattice potential following axial displacement of the trap. The oscillations are shown to be strongly suppressed on the scale of the displacement, and to have a characteristic small amplitude, damped behavior in the collisionless regime. The presence of a separatrix in the semiclassical Brillouin-zone phase space is predicted and shown to produce strongly asymmetric phase-space distributions as a function of the trap displacement.
