It is possible for laptops even circa 2004 to enjoy the two-finger scroll functionality of the more modern apple macbooks.
To enable this feature, you must edit your xorg.conf file
locate the module section and add a line to load the synaptics driver if it is not already there.
Section "Module" Load "synaptics" EndSection
Then locate your TouchPad entry (i.e. Section "InputDevice") and add the following parameters:
Option "VertTwoFingerScroll" "1" Option "HorizTwoFingerScroll" "1"
Restart your services and you will now enjoy horizontal and vertical two-finger scrolling on your linux laptop!
