I have the same issue with my Acer 532h. On the old Ubuntu release it was treated as a PS2 mouse with no touchpad options, and now it is treated as a touchpad with no scrolling. The fix to set it as IMPS is horrible because you do not get the touchpad features like disabling touchpad will typing (which is a must have feature).
