There is -one- Mac edition of r5xx actually :-) I have one of them...
It's PCIe and came as an option for the PCIe latest generation G5s. At
some point Alex gave me a BIOS ROM file that we could use to get the
ATOM stuff from, but we never quite sorted out distribution and so never
added mechanisms to use it from the driver.
