Look at the permissions for 'font.dir', 'font.alias' in those
directories and make sure they are at least root-readable. If they are
try to rebuild them with:

mkfontdir /usr/X11R6/lib/X11/fonts/Speedo
ttmkfdir /usr/X11R6/lib/X11/fonts/TTF
xset fp rehash

See if they are readable now. Try to restart xfs as well if rehashing
doesn't do it.
