While we wait for that I have here a counter patch for the font engine.

If there are no comments about it in near term this will be committed to
SVN.

To use automatic font conversion (unifont.bdf->ascii.pf2 and
unicode.pf2), install bf-utf-source (ubuntu and probably debian). Font
converter uses Java temporary. So when font compilation is enable font
converter will be compiled and executed. Otherwise Java is not needed in
anyway. Tested with Sun Java 1.6 on x86-64.

grub-mkconfig should generate new grub.cfg with changed font commands.

To convert custom fonts look for ascii.pf2 in Makefile.in and use
matching commands to convert your fonts. These will be documented on
Wiki once committed.
