You'll need to modify /etc/X11/fs/config removing TT directories or putting them at the end of the list
and by moving 100dpi fonts to the top of the fontpath. Here I rem'med out the old settings. Some
tinkering on whether to include TT fonts at all here  might be necessary.

=============================================

# Default font server configuration file for Mandrake Linux workstation
#

# allow a max of 10 clients to connect to this font server
client-limit = 10

# when a font server reaches its limit, start up a new one
clone-self = on

# alternate font servers for clients to use
#alternate-servers = foo:7101,bar:7102

==============================================

Now in the section for fonts in /etc/X11/XF86Config. Note - "unix/:7101" is for the xfstt server.
/usr/local/share/fonts/truetype is the newly created TT font directory.
