As a data point, all the PCI machines I have here that are turned on
have at least one device with a latency timer of 0.  Most of these are
bridge type devices, including the Alpha pc164's sio PCI-to-ISA bridge.
But I also have various USB, audio and IDE controllers that have 0 for
the latency timer too.
