Which means you don't have device acpi configured into the kernel.

That's because you have device isa configured into the kernel and
the acpi attachment was coupled to device isa. I uncoupled it with
the commit, because device acpi needs to be able to exist without
there being a device isa. So, the acpi attachment for ppc(4) exists
only when device acpi is configured in the kernel.
Alternatively, someone needs to make a module for ppc(4).
