I'm sorry no one answered.  I don't know about root-only, but it
makes sense for the "set" operations to be governed by write access
to the device.  That is consistent with the BSD/*nix model.

Reading should be governed by read (FREAD) access to the device,
modifying/setting/writing should be governed by write (FWRITE)
