Just a curiosity, i've only two powerpc machines[1] equipped with PCIE videocards and both them are not able to boot with radeonkms. Modern PCI-E videocards are not recognized by the old linux framebuffer subsystem and they solely can be managed by the new KMS frame buffer that doesn't work properly on Power Architecture.

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.
