What is the syntactic thing in this example which distinguishes
"user can toggle this" (ESP_PCI, ARM_VIRT, SUN4M) from "user
can't toggle this, it's just an internal thing selected by
other nodes" (the rest) ? I'm assuming we'd have some sort
of UI thingy that presents the user only with the user-settable
options.
