I agree that this is the right direction to go in. The number of acpipnp
devices that are also pnpbios or (even worse) isapnp is (a) unlikely to
increase, and (b) *very* small, and pretty much limited to superio and a
small number of sound cards on old laptops. We may come up with a better
solution for them later, but right now shifting away from requiring that
every new ACPI device driver also bump a whitelist is an improvement.
