I may be able to - one of the downsides though is that many of these systems had hard-coded scripts which started a getty on the original port - and that kind of makes it difficult to sort out. This kind of change becomes very much one of Linus' "flag days".
So I'd suggest that we have a period where the old driver is still available, so at least people can choose to use the old major/minor numbers for a while.
