Easiest, but not necessarily the cleanest.  I might want to install
FreeBSD systems in a public user area (yes, this debate again) and
allow users to modify the keymap to their liking, via ~/.login, for
instance.  I'd want to disable assigning `boot' to any of the
keys, though.

Not the keystroke, just the action that goes with it.  Of course,
modifying the kernel to do this still doesn't ring true.  Kernel
config sounds nicer, though.
