Simplest fix is to shuffle Makefile. But better is to create an acpi "module"
so the namespacing just works, something like below. Overriding MODULE_PREFIX
only works for builtin code anyway. (Which makes sense: moving a parameter
from one module to another isn't a change we can cover up).
(Sam: foo-objs-y would make this neater)
