Yeah I think the interface is settling down. You should be able to look at
the code in drivers/acpi or drivers/hotplug/acpiphp* for examples.

Indeed, I think a sonypi driver that assumes ACPI will be much shorter and
look quite different from the current one. But since we have resolved the EC
contention issues, this need not be addressed immediately.

PS IIRC there is the idea of a "platform enumerator" that will suitably
generalize the mobo enumeration function ACPI performs on x86 for other
platforms, but I don't think that has been implemented yet.
