I've updated spot's excellent rpm package to the latest 18.104.22.168 for Fedora 17 and 18.
It changed quite a bit from the old one; and it works fine on my systems (both 32 and 64 bits).Any constructive comment is much appreciated.
I've asked spot if he wants some help on mantaining it; in the meanwhile I've posted a new repository.Repositoryhttp://slaanesh.fedorapeople.org/steam/
To install, simply download the repository file and install steam through yum.RPM Fusion
To make it work in Fedora, the "rpmfusion-free" and "rpmfusion-nonfree" repositories are REQUIRED.
rpmfusion-free: libtxc_dxtn for S3 compression library if you use nouveau/radeon/intel
rpmfusion-nonfree: xorg-x11-drv-nvidia/catalyst for proprietary drivers
To enable them, perfom the following (replace 18 with 17 as appropriate):
Fedora 18:Nvidia / AMD proprietary drivers
Since I've not backported all the base Fedora packages as spot did, on Fedora 17 it should work only with the proprietary drivers.
For 64 bit systems you need to install ALSO
the 32 bit libraries in addition to the above.
# yum install xorg-x11-drv-nvidia-libs.i686 or xorg-x11-drv-catalyst-libs.i686
