Below you find a little utility that I've written to enable
fonts given as AFM/PFB files under X11. I needed those fonts
for StarOffice/Linux and thought the utility might be use to some
of you:

Usage is pretty simple: cd to the dir where you've stored the
AFM/PFB files (it has to be on the font path of your server)
and let the script run. Then tell the X11 server
to load the new setup with 'xset fp rehash'. That's it.
BTW, the CorelDraw CDs include tons of these fonts...
