I agree it's probably not easy, but I think having the right semantics is more important than fitting cleanly into the driver model. But I know that without code, I'm just venting hot air, not contributing to a solution. How's the ACPI driver model integration going, anyway? I seem to recall some patches a while back, but I don't think they're in the tree yet. > Do we really need the memory hotplug device returns pnp0c01/pnp0c02? > What's the purpose? I don't know. But I think Keith already determined that a BIOS change is not likely. I hate to ask for BIOS changes like this because it feels like asking them to avoid broken things in Linux.
