Isn't this used on all ppc440+ as well? I don't think PS3 has it either, it should only be the second generation Cell blade doing this, which uses ppc440-derived I/O devices. We will probably see a bunch of the same devices on APM's X-gene ARM64 machines as well, but we don't have to maintain a stable device name for those yet. Arnd
