FWIW ... after thinking about it and some of the other debug I've had to do,
maybe acpi=no_memhotplug and acpi=no_cpuhotplug are in order here.  I've had to
disable both during hardware enablement debug and it seems that it "fits" the
current acpi disabling scheme.

Unless, of course, Rafael still objects.
