I had the same problem with a recent 15 inch powerbook (from May this
year) -- indeed the trackpad (or touchpad) is not supported, and it
seems like the trackpads on recent powerbooks are are quite different
from the supported trackpads.  See
http://johannes.sipsolutions.net/PowerBook/touchpad and
http://www.popies.net/atp/ . I have written a klugish version of that
driver that I have been using for a few months.  Unfortunately, it
does not work very well (sometimes there are random fluctuations
(probably due to heat) and sometimes no motion is detected), but if
there is interest, I could clean it up and post the driver.  (I just
noticed that there is a new version of the atp Linux driver -- maybe
they have figured out a better way to interpret the input generated by
the trackpad.  I will check, but do not hold your breath.)
