Given that the "quiesce" service isn't part of the Open Firmware standard nor of one of its supplements as far as I can see and given this service isn't available on sun4u I'd prefer this implementation to be entirely moved to MD parts instead (similar to the "SUNW,<foo>" services which we keep MD).
