That's too broad a statement, it works fine on other PowerPC machines
(PowerMacs, some embedded boards).

It looks like there's a problem with accessing the PCIe device memory,
and at this point it's not even 100% clear that this is due to a problem
in the driver, as opposed to e.g. in the platform code.
