ACPI is mandatory for amd64 and ia64, but it is optional on i386.
Because it is optional, it is a module so that the loader can only
load it on machines that support it. I think the ppc module should
be changed to include the acpi attachment personally, assuming that
the ppc module already includes the ppc isa attachment.
