It requires a bit of legwork, but most of the free (as in beer) font
sites have a number of libre fonts - you just have to sort through all
the free-/dontation-/shareware to find the good stuff.
I happen to like
dafont.com because they list font licensing information
without having to click through. Here's a few nice looking ofl/gpl fonts
I found fairly quickly:

http://www.dafont.com/tuffy.font
http://www.dafont.com/jura.font
http://www.dafont.com/aurulent-sans.font
http://www.dafont.com/resagnicto.font
Hope this helps! :)

Thanks to everybody, got a few great looking fonts so Fusion Linux is
going to look very slick with such cool fonts ;)
