Yes, it is for 3.1. There is a line in the PR saying this, but in
somewhat unobvious ways; in the Environment section, there's both uname
output showing 3.1 and a line saying "hpcfb.c,v 220.127.116.11".
Admittedly, neither is particularly obvious to someone looking for the
meat of the PR; I should have called this out more clearly elsewhere.

ls -1 and ls -l will probably be even better. The more adjacent lines
resemble one another, the faster it'll scroll, since the way it works
is by not redrawing character cells for which the old and new
character-and-attributes are identical.
You're welcome. Next use of round tuits on this code: bring back jump
scroll (which, as you may have noticed if you read it over, was a
casualty of my work).
