That makes the following code in openfirmware_core odd:

#if defined(AIM) && !defined(__powerpc64__)
        /*
         * Clear battable[] translations
         */
        if (!(cpu_features & PPC_FEATURE_64))
                __asm __volatile("mtdbatu 2, %0\n"
                                 "mtdbatu 3, %0" : : "r" (0));
        isync();
#endif

No need to test AIM.

I assumed too much from seeing that AIM test.

Sorry for the noice.
