It sounds like you have at least the video drivers functioning, if not
the mouse...

Have you verified if the synaptics package itself is installed:

  rpm -q synaptics

If not, is this laptop connected to the Internet?  If so, you can do:

   yum -y install synaptics

This will install the synaptics package, though doesn't install the module.

Once this is done, you can look at the xorg.conf file itself. If
you're not familiar with vi, there's another editor called "nano" that
may be easier the first few times (after that, it pays to learn vi).

The main things you need to verify are the following sections in the xorg.conf:

Section "ServerLayout"
    Identifier     "Layout0"
    Screen      0  "Screen0" 0 0
    Screen      1  "Screen1" RightOf "Screen0"
    InputDevice    "Keyboard0" "CoreKeyboard"
    InputDevice    "Synaptics" "CorePointer"
EndSection

Section "InputDevice"
    Identifier     "Synaptics"
    Driver         "synaptics"
    Option         "Device" "/dev/input/mice"
    Option         "Protocol" "auto-dev"
    Option         "Emulate3Buttons" "yes"
EndSection
