Thanks. I've tested it here on a e6230 (bios rev 08), and it gets
correctly detected (but twice?):
input: AlpsPS/2 ALPS DualPoint TouchPad as
/devices/platform/i8042/serio1/input/input14
input: AlpsPS/2 ALPS DualPoint TouchPad as
/devices/platform/i8042/serio1/input/input16
But the input events seem very noisy (E.G. the cursor jumps up and down
if I keep my finger pressed on the touchpad). Especially the Y
coordinate seems unstable:

Any idea why? Do you see this as well?
