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.
