Couple of days went and now patch finally went in. I have updated
gfxterm part of the wiki to match new font enngine:

As a temporary workaround Java is being used to convert fonts. This
means that it would be wise to have Java SDK & VM installed when
executing make. During build process it looks for /usr/src/unifont.bdf
and if found converts it automatically to ascii.pf2 and unicode.pf2
(Previously those were ascii.pff and unicode.pff).

loadfont command can be used to load PF2 fonts.

lsfonts command can be used to list loaded fonts.

However there is a slight incompleteness in unifont.bdf that does not
feature name nor point size. And we get "Unknown -1" as a output for
default unifont.bdf font.

You are also free to experiment with other BDF fonts. gfxterm has been
updated to try make every font terminal compatible. It looks for every
ASCII font found and then determines default font width from there and
uses it to determine glyph spacing. When graphical menu is integrated in
there font spacing will be what ever is configured in glyphs.
