Comment(by dsd):

 The kernel attached at the start of the ticket is based on source from
 http://dev.laptop.org/~pgf/junk/sentelic/. The code is quite different
 from what ended up in the kernel, but (by default) presents a relative
 input device that would not have been picked up by the synaptics userspace
 driver.

 I just tested the in-kernel sentelic driver on XO-1.5 on olpc-2.6.35, it
 works fine, including using clicks and gestures to resume (even though
 they are massively truncated as normal). The magic needed to make the pad
 behave like we want, which will be done by olpc-utils, is:

 {{{
                echo -n 0 > /sys/bus/serio/drivers/psmouse/serio*/vscroll
                echo -n 0 > /sys/bus/serio/drivers/psmouse/serio*/hscroll
                echo -n c > /sys/bus/serio/drivers/psmouse/serio*/flags
 }}}
