Yes, I'm sure. It is the recent iBook with the "scrolling trackpad". All
former models of iBooks had ADB trackpads.

Here the relevant part of lsusb -v:

I have already corrected the number in your wiki some days ago ;-)

There is a section for the appletouch driver:

Why do you write "synaptics driver"? AFAIK there is no synaptics driver in
the kernel, only a synaptics driver for X11, which can be used
additionally to get some special features like scolling:
