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.
