	Now I'm confused. According to setfont(8), there are two kinds of
maps (not counting the keymap): the console map (option -m) and the
unicode font map (option -u). What you describes appears to be the
unicode font map but that still leaves the other one.

	BTW, which does FONT_MAP refer to? I tried to grep through /etc to
see how it is used in the initscripts, but this only shows the
vconsole.conf entry...
