I mean that the original implementation is incorrect and this is just
continuing the problem - the reason that we don't want to have this
stuff hard coded in the device drivers is that we should be doing this
sort of configuration in the machine drivers so only the relevant
systems are affected by configuration updates.  Putting this in the
drivers tends to lead to a series of configuration changes like this.
