are we sure that adjusting acceleration is as important with an
f11 release?  i have the impression that the default algorithm is
quite a bit better than the old one, and doesn't need the
adjustment as much.  i confess i haven't used a recent XO-1
release extensively, but i'd rather not see us add controls where
none is needed.

anyway, according to a recent xset man page, values of $N between
30 and 40 in "xset m $N/20 0" are recommended (the man page
actually says between 3/2 and 2).  a slider might want a little
more range than that, but not much.  and as with the pentablet
setting, there needs to be a way to re-init this at session
startup, and a way for the slider to learn the current value directly
from X (perhaps via xset, or perhaps more directly).
