I can confirm that you can also use these "alternate" fonts for newspaper subscriptions. And for serif-hating readers like me, it's definitely nice to be able to use something darker than Avenir.
I copied the entire contents of /usr/local/calibre/resources/fonts/liberation/ from my Calibre installation to my /media/KOBOeReader/fonts/ and now I have a nice dark LiberationSans to read with.
I'm only assuming, but I imagine that copying over all four font files is required for "best" font viewing, so that italics and bold will all be rendered at their finest. For whatever it's worth, even with all four files in the fonts directory the Kobo's font chooser only shows "LiberationSans":
LiberationSans-BoldItalic.ttf
LiberationSans-Bold.ttf
LiberationSans-Italic.ttf
LiberationSans-Regular.ttf
