x86_64 uses ACPI to do memory hotplug on real platforms that support it.

I actually included the probe file for x86_64 way-back-when for
convenience,
so you'll find it there.  Of the x86 platforms that I know that also
support
memory hot-plug, they also use ACPI - however, these systems are x86-64 
as well, so usually they aren't running 32-bit, but 64-bit.  x86 doesn't

include probe file, but you could easily add it as someone else
(Kame-san?) 
pointed out.  Good luck...
