So this does the job but with this patch you introduce a compile bisection
bug, which is a not good. The way around is that in this patch you also
introduce temporary scaffolding so that the drivers can build. Something
as simple as an function that calls the new version, but has the right
arguments. Then the next patch (the one that actually does change
the backends, will back that wrapper out).
