Bug#617196: grub-pc: GRUB_GFXMODE silently ignored if font unavailable

[Ben Longbons]

I managed to fix the core problem by doing:
cp /usr/share/grub/unicode.pf2 /boot/grub/unicode.pf2
Obviously it can't read any partition but /boot since it's on encrypted LVM.

For some reason, other computers I've looked at *do* have the font in
the right place.

It's still a bug that the fallback to text mode is silent though.
