Confirmed not working on my Acer Aspire 5740 w/ synaptics touchpad.

synclient -m 100 reports single-touch only.

Here is my xinput list-props output:

I can see that Capabilities is reporting no multitouch support, but the "spazz" behavior that other users have reported seems to indicate a hardware understanding of multitouch that isn't being properly recognized by xinput. Can we force xinput to see the touchpad as having multitouch capabilities to see if it perhaps it's just a device recognition error?
