Let's be clear here, the pre-EV56 Alpha CPUs do provide an atomic one-byte and two-byte load and store; it's just that one must use locked load and store sequences to achieve atomicity. The point, I think, is that the pre-EV56 Alpha CPUs provide non-atomic one-byte and two-byte load and stores as the norm, and that is the problem.
