Thanks.  Reverting
ftp://ftp.kernel.org/pub/linux/kernel/people/akpm/patches/2.6/2.6.17/2.6.17-mm4/broken-out/x86-dont-print-out-smp-info-on-up-kernels.patch
will fix it.

<looks at davej>

That patch is pretty yuk anyway

 void module_arch_cleanup(struct module *mod)
 {
+#ifdef CONFIG_SMP
	alternatives_smp_module_del(mod);
+#endif
 }

Should be a stub in a header file, which would fix this problem too.
