Bug#1024447: Also affects gfxmode

[Ralph Martin]

I'd just note that the bug is not just limited to producing odd 
characters round the border.

Failure to load the font also causes a block of config code to be 
omitted, in my case this is:

if loadfont $font ; then
   set gfxmode=1024x768
   load_video
   insmod gfxterm
   set locale_dir=$prefix/locale
   set lang=en_GB
   insmod gettext
fi

which has a more serious effect - the gfxmode is not set, and if you 
have a high resolution screen, the grub menu becomes too small to read.
