Have you also changed your locale? F8 defaults to UTF-8 locales, whereas people usually set up RHEL3 with an 8-bit locale. That changes the font selection, and you may find that running in en_US works whereas en_US.utf8 does not.
Note that the font you quote is an 8 point 100dpi font, at 11 pixels not points. What you actually need depends on the dpi of your screen, and if that is less than 100 dpi you need the 75dpi fonts. Another idea is to install the scalable fonts in the urw-fonts package, and use something like foo <- getOption("X11fonts") foo[1] <- "-urw-nimbus sans l-%s-%s-*-*-%d-*-*-*-*-*-*-*" options(X11fonts=foo) to select them.
