I generally like the direction this is headed.
But I wonder whether it's right to expose the distinction between
PNP devices and ACPI devices to userspace.
Assume you had a box where you can run either PNPBIOS firmware
or ACPI firmware. Since the box has exactly the same hardware
in either case, it would be nice if everything in /sys and udev
stayed the same.
Is it possible to extend the PNP model to include ACPI, rather
than introducing a new ACPI model alongside the PNP model?
