Bug Description
Binary package hint: linux-image-2.6-386
On my MacBook, which uses the appletouch kernel driver and the synaptics X11 driver for trackpad support, the pointer acceleration
can't be changed. Attempts to change this acceleration by using the GNOME mouse control panel, gsynaptics, and manually editing Xorg.conf have been unsuccessful.
Using the usbhid driver, pointer acceleration can be changed. This seems like a bug in the appletouch driver - could this driver either be 1) up[dated to fix the issue or 2) removed in favor of standard usbhid. Preferably the former, as usbhid doesn't support advanced features (tapping, scrolling,etc) - though proper acceleration seems more important.

Apparently, doing an rmmod appletouch and a modprobe appletouch will fix the problem until X is restarted.
At that point, the previous behavior returns, and you have to redo the rmmod and modprobe commands...
