After deinstalling nvidia-drivers, removing "nvidia' from VIDEO_CARDS, performing 'emerge -vD world' and trying to reinstall nvidia-drivers I get the following output: root@lynx:/usr/local/portage/media-video(79)# emerge -pvD nvidia-drivers These are the packages that would be merged, in order: Calculating dependencies ... done!

Correct they don't work with x11-base/xorg-server-1.7*. You need to wait for nvidia to release a version that supports it.
In principle, nvidia-drivers-190.36 or later should compile with xorg-server-1.7. In practice there are still issues that prevent combinations of nvidia-drivers and xorg-server-1.7 to work properly.
