I strongly suspect that at this point most people will in fact have one of the several tools that preceded kmscon by some years and are still around: zhcon (http://zhcon.sourceforge.net/), jfbterm (http://jfbterm.sourceforge.jp/), fbterm (https://code.google.com/p/fbterm/), yaft (https://github.com/uobikiemukot/yaft), fbpad (http://repo.or.cz/w/fbpad.git), and so forth.
