I guess this won't change much, but I think this is definitely needed:

For comparison:

./amdgpu/files.amdgpu:device    amdgpu: drmkms, drmkms_pci, drmkms_ttm, amdgpufbbus, firmload

I see that autoconf(9) mentions:

    config_mountroot(dev, func)
         Called by the child to defer the remainder of its configuration
         until the root file system is mounted.  At this point, the
         function func is called with the argument dev.  This is used for
         devices that need to load firmware image from a mounted file
         system.

Is this the case here? I'm not sure if the file system must be mounted or
how this works if not.
