Yes, you will need to tell X about them.  To do freetype, we need to get
the actual font files, not just what X font servers give us.  You should
add lines to your /etc/X11/XF86Config-4 to look something like this:

Section "Files"
        FontPath        "unix/:7100"                    # local font server
        # if the local font server has problems, we can fall back on these
        FontPath        "/usr/lib/X11/fonts/misc"
        FontPath        "/usr/lib/X11/fonts/cyrillic"
        FontPath        "/usr/lib/X11/fonts/100dpi/:unscaled"
        FontPath        "/usr/lib/X11/fonts/75dpi/:unscaled"
        FontPath        "/usr/lib/X11/fonts/Type1"
        FontPath        "/usr/lib/X11/fonts/Speedo"
        FontPath        "/usr/lib/X11/fonts/100dpi"
        FontPath        "/usr/lib/X11/fonts/75dpi"
EndSection

(modified for you being on RedHat of course.)  Yes, I know it sucks that we
can't use the X font server stuff, but it just doesn't give enough info.

We will eventually move to Pango.  Not yet, though.

That would be rather interesting.  Can you get any message_* to show?
