Because it's different for trackpads in relative (0x03) or absolute
(0x00) mode.

It's right, but it's not an emulation: trackpads on adb bus of every
quite recent ibook/pbook are from Synaptics. The adbhid driver uses
tpad in relative mode, this[1] kernel patch simply initialize and
manage tpad in absolute mode. In this way you can use synaptics_drv in
XFree/Xorg.
