I've found that properly configuring synaptics fixes the problem, and also gets rid of an issue where leaving the ibook to sleep for more than a critical amount of time (which I wasn't able to determine, around 10 minutes) leads to a dead touchpad on wakeup.
here is the interesting part of my /etc/X11/xorg.conf file:
Make sure that "Device" points to "/dev/input/mice" (this was broken in my autoconfigured xorg.conf). Also make sure to use InputDevice "Synaptics Touchpad" in ServerLayout (this was also broken).
if /var/log/Xorg.0.log complains that the synaptics module doesn't exist, try apt-getting xserver-xorg-input-synaptics (apparently the previous
xorg-driver-synaptics fails to make the driver available to xorg).
