In the case you have Synaptics touchpad (a good chance), you could install "ksynaptics" package (KDE) or gsynaptics (GNOME)
Then, for example in KDE, when you go to "kde settings" or "personal settings" - there should be a new "touch pad" option under "peripherals". Playing around with that should let you set the settings you like..

I hope you have either of those in FC repositories. If not, I guess you can find an RPM from somewhere, perhaps at pbone or similar.
