I'm almost certain that there is a hardware requirement. You can enable the option as this guy did, but if your touchpad isn't able to detect more than 2 fingers (like mine), nothing will happen. This is just a case of But-It-Works-For-Me.
In fact, I was able to activate two-finger-scroll on my touchpad. But I did it with a dirty mod of the synaptics driver, and it has nothing to do will how many finger are detected, but rather with the fact that one and two fingers give different pressure. Measuring the pressure is a safe way to tell if there is more than 1 finger on the touchpad.
There is a safe and certain way to know if your touchpad has the ability to detect multiple fingers. For this purpose you need the program
synclient. (I'm not sure where I have it from. Google it.)
Start it like this:
The output looks like this:
Code:
~ $ synclient -m 100

The
f column is the number of fingers currently on the touchpad. If you see the number 2 when you try to scroll with 2 finger - congratulations, you can enable multi-touch (or, ahem, double-touch). Otherwise, you are out of luck.
Also, ALPS touchpads, which are not Synaptics touchpads, also use the synaptics driver. ALPS touchpads generally don't support multitouch, while Synaptics touchpads mostly do. (Words taken from the manual of synclient).
