as i said the other day, the kernel driver should either do no scaling
by default, or it should make every pixel on the screen touchable with
a "standard" pointing instrument (i.e., a stylus).  the latter is what
it does now -- perhaps exaggerated.  but any other midway decision
between those extremes (which i agree is probably the right thing)
constitutes policy, and therefore belongs at user level.

which is to say, i think the correct defaults belong in olpc-utils,
along with the countless other XO useablility tweaks that are already
there.

(once that change is firmly in place, i'll probably revert the driver to
default to no scaling at all.)
