(speaking only for XO) No. We would have to change mouse driver which
introduces a handful of regressions, will need some real effort to
resolve. See the discussions earlier in the thread.

The most realistic quick-fix option I can think of is adding a small
hack into the psmouse driver in the OLPC kernel, which sends the
single command needed to disable tap-to-click. Last time I looked at
this code I remember thinking that this would be quite easy, since the
more-powerful synaptics driver doesn't actually change the mode of the
mouse, it just takes advantage of a whole load of non-standard
commands.
