In TidBITS-157 Jim Burmeister reposted the hack that you can perform on ATM 2.0.2, 2.0.3, and 2.0.4 to make it work correctly with System 7.1. At the end of the article he says that the hacked version of ATM won't work under System 7.0 anymore. I managed to make that hack work with 7.0. It is a simple bit of ResEdit work, and remember the usual Surgeon General's warnings about working only on a copy of the file.

Open a copy of the System file, and then open the fld# resource. Add another entry to the end of the list of these "special" folders (extensions, Print Monitor Documents, Control Panels, etc.). Call the folder "Fonts" (or whatever you want) and give it the four-letter abbreviation "font" (just as you did in the ATM driver). Save, quit, restart with the copy and you're done. The System will create that special Fonts folder automatically on restarting. From now on you MUST put all your PostScript fonts in this folder. Keep in mind that you MUST use the hacked version of ATM for this to work, and the Fonts folder we've created will NOT work like System 7.1's Fonts folder.
