Thanks! I found it. :-)

You can ALWAYS search with a / in make menuconfig (leading CONFIG_ is not
necessary).
Hidden options do not show up until precedents have been enabled. I had to
enable a couple of the HOTPLUG options and then it showed up.
But / should (a) tell you where it is, and (b) tell you what to enable
to make it appear.
That's what Peter meant when he said / will always find it. / won't make
it appear, it tells *you* how to make it appear.
