The touchpad in Dell Vostro 1015 doesn't have touchpad features such as scrolling to the right of the pad. X doesn't use the synaptics driver but see it as "PS/2 Generic Mouse", probably because "/lib/udev/input_id /class/input/event4" says "ID_INPUT=1 ID_INPUT_MOUSE=1", probably because of how the kernel detects it.

I would expect that the kernel somehow detected it as a synaptics device.
kernel-PAE-126.96.36.199-0.fc15.i686, but same problem seen with 3.1 rc8.
This has an ALPS touchpad. There's an open bug for tracking the driver as it gets worked on upstream.
