During the testing phase, a change was made that allowed synaptics to be 
configurable by running
system-config-display --reconfig

The needed information will be inserted into the xorg.conf file. So you 
were on the right track with running system-config-display on the 
system. When X is restarted, the touchpad should work.

I seem to remember mention that this does not yet work for the alps 
version. Checking the fedora-test-list archives might be useful to find 
information.

One nice thing on my laptop during the upgrade was that the touchpad 
worked while upgrading. This was a welcome feature for the installer.
