    In-order execution doesn't preclude speculative execution (branch prediction etc.).

    ...and the POWER6 as well (which can do speculative execution, though, so is vulnerable). But yes, Cell BE and Xenon/XCGPU may not be able to do speculative execution in which case they wouldn't be vulnerable.

    Edit: added link regarding POWER6
