I wrote a program to calculate this and came up with the following figures: 7.22e+040 when no piece occurs more frequently than in the starting position, e.g. noone has 3 knights or 4 bishops. 2.95e+042 when no piece occurs more frequently than in the starting position, except that either side may have up to 2 queens. These are not exact estimates, as they do not take into account king not on move in check, illegal pawn positions, en passant or castling.
