    Thanks for showing that that patch didn't work. I should have
    remembered why it wouldn't. The next step would be to try a workaround:
    Comment out the two calls to drm_initmap() in radeon_cp.c.

    We really need a nice call to grab the start/offset of a pci resource
    given the rid. We can avoid it now, but we might not be able to given
    where the DRM is headed.
