    At a hardware level, the interface for the Zacate/Ontario APUs is like the Evergreen discrete GPUs. Think Cedar aka HD54xx.

    Default bus?

    errr....
    I was actually thinking bus interface. I guess it's not anymore PCI-E.

    It still shows up as a pci device and is accessed the same way from a software perspective.
