If you look after what is deployed by net-misc/suite3270 you can see an Adobe PCF font named 'x3270':
$ equery f net-misc/suite3270 | grep fonts
However the menu chhoice "Options->Fonts->3270 Font (14 point)" is greyed out in x3270. The reason for this is that Xorg is not aware about the exitence of this newly installed font.
you have to either manually issue a :
xset fp+ /usr/share/fonts/x3270 && xset fp rehash
Or to make this persistent, add a "FontPath" statement in a "File" section in your Xorg configuration. This latter step could be done by the ebuild, providing a better user experience.
Tested with net-misc/suite3270-3.5p12 (Suite 3270 3.5 GA 12) and net-misc/suite3270-3.6p8 (Suite 3270 3.6 GA 8).

Make the ebuild push a new FontPath in Xorg configuration and be a little more friendlier to the sysadmin on what to do next :)
i would assume the font eclass would handle this for us rather than having to do random package-specific hacks. hopefully they have recommendations.
