This is not how distros work today. All code/patches must come from upstream
and all code/patches must be cross-architecture. There are exceptions, but
only for very critical things.
Furthermore, the right answer to avoid upgrade pain is to fix things upstream.
So lets try to find a solution that we can integrate.
