The tarball ships a rpm spec file which can help build the binary rpm package. You can try to use:
rpmbuild -tb laptop-mode-tools-1.XX.tar.gz
This should create you the final rpm binary package.
(This command should work on any RPM based distribution. If you run into any problems, please report)
Download the package and install it using the following command:
rpm -ihv laptop-mode-tools-y.xx-1.rf.noarch.rpm
where y.xx should be replaced by the version number.
As an alternative, you can subscribe to the DAG RPMforge repository, which generally contains recent packages for Fedora.
