The FreeBSD-questions list has posts which suggest that the "feature" I discovered today (
vim can run in a small-font vidcontrol without X ...) may not persist, at least at first, in the new version(s) without syscons or some other part of the code upgraded to permit it. [ Partly posting just so persons who use the same terminal, can try it out... (v9 not VT...) if they have not already ].
