Probably something - what will be interesting is if someone can figure out not only the speed, but also the direction of the spin. There's no guarantee that the inner core is actually spinning along the same axis as the mantle/crust. Seems possible that an offset of a few minutes between the axes of rotation might explain why the magnetic poles are not exactly matched with the rotation axis of the earth.
