I tore apart our fontconfig packages (32 and 64 bit) and guess what? Yep, they provide a proper /etc/fonts/fonts.conf file with lots of stuff enabled. I know we had an X,org upgrade at one point. I wonder if that had something to do with replacing the file. In any case I definitely don't know the source of the problem and I think I need to ask the developers to take a look.
Sorry I wasn't helpful on this. I thought I could be.
