The 7.e. section of Gentoo Handbook (named Kernel Modules) contains information that is now longer valid (at least not for fresh installation). According to http://www.gentoo.org/doc/en/openrc-migration.xml the way to specify the modules that should be loaded automatically has changed with openrc.
It's still correct for stable users. ~arch OpenRC users have their own setup, as detailed in the guide. The handbook won't be changed, as the stage tarballs and all configs track the stable tree.
