For anything newer the latch is still there in the chipset; most likely in the south bridge and probably actively decoded (irrespective of the architecture of the bit behind the north bridge) though it may be possible to disable it in a chip-specific manner. If there is no south bridge in a given system, then it is probably safe not to claim the port.
