However, I'm not saying that the hardware should not segment things into however many pieces that it wants / needs to.

The problem is fitting that into an interface which wholly doesn't fit that particular requirement. It's not that difficult to imagine different ways to represent however many memory slots, right? It'd take work to make sure that integrates well with whatever tooling or use cases but once done this particular problem will be resolved permanently and the whole thing will look a lot less silly. Wouldn't that be better? Thanks. -- tejun
