Please test the patch at http://www.FreeBSD.org/~jhb/patches/smp.patch
You can apply it to a sys/ check out by using patch -p6.  It moves
the setting of mp_maxid into a separate function (cpu_mp_setmaxid())
that is called before loader tunables so that UMA and others can use
it.  cpu_mp_probe() is now called at SI_SUB_CPU / SI_ORDER_SECOND like
it used to be.  This is necessay to re-enable the ACPI module on i386.
I have tested it on i386 but not on other archs.  Please be sure to
test that a normal SMP kernel works as well as booting an SMP kernel
with 'kern.smp.disabled'.  cpu_mp_probe() is no longer called if SMP
is disabled in the loader using the tunable.  Thanks.
