Was thinking x386, but it seems to use the same scheme for data or program addresses; candidly, I believe building a jump table for function-pointer calls just like interrupt vectors may be your best bet; as it will only add a few cycles per call through a data pointer, and may even be eliminated if the code never calls a function pointer (which most code never does).
