• Remove the hack to prevent the acpi module from loading.
• Add a really, really, nasty hack to provide stub versions of all of the 'device apic' functions used by the ACPI MADT APIC enumerator if 'device apic' is not compiled into the kernel. This is gross but is the best we can do with the current kernel linker implementation.
