 This is not related to acpi at all ... but with recent change where
 the procfs module was removed from the builtin list, and loaded from
 the filesystem when needed.
 
 The `/proc/stat' code depends on MULTIPROCESSOR define/option which is
 not set when standalone module is build.
 
 While it's easy to fix for both i386 and amd64 where MULTIPROCESSOR is
 mandatory for quite some time, i'm not sure how to properly handle it
 for other archs ...
