That works for most (and should make your two finger scrolling work just fine), however it didn't for me. Then I came across this post: http://www.cnpbagwell.com/linux/fedora-13-and-asus-eee-pc-1005peb (see the Touchpad section). I didn't dig as far Chris Bagwell did, but taking his suggestion on trying the two finger emulation, everything worked perfectly on my Gateway LT21. The two lines below are what I used:
Option "EmulateTwoFingerMinZ" "35"
Option "EmulateTwoFingerMinW" "8"
Here's a web version of synaptics man page that shows most of the options available for your synaptics driver version: http://linux.die.net/man/5/synaptics. Of course, to see a list of the options that your current driver supports, run this at a term:
man synaptics
As of writing, the latest version is 1.2.2. To update in Fedora run:
sudo yum update xorg-x11-drv-synaptics
Good luck.
