In the standard model, CP asymmetries in the B^± → π^± K channels are about 2% based on perturbative calculation. Rescattering effects might enhance it to at most (20-25)%. We show that lepton-number-violating λ' couplings in supersymmetric models are capable of enhancing it to as large as 100%. Upcoming B factories will test this scenario.
