The options are mentioned in the Changelog of frenchb.pdf:v2.0d \frenchbsetup: Options og and fg changed: limit the definition to French so that quote characters can be used in German. Unfortunately, there is no date given, but it is more then 4 years at minimum.
TeXlive 2012 comes with: \ProvidesLanguage{frenchb} [2010/08/21 v2.5a French support from the babel system] So indeed version 2.0d is pretty old. JMarc
