Nope.

Here's the diff of the two grub.cfgs with all path based differences
removed:

(Yeah, I forgot to set the video=atyfb:off in the /etc/default/grub.
But since we didn't come so far anyway, it shouldn't matter.)

grub-common contains /usr/share/grub/unicode.pf2 and this seems to be
referenced in Debian's version of grub.cfg.

No more found in any version of the grub.cfg and locate only found it
in your build directory.

Probably not the right thing:

set root='(vg0-usr)'
search --no-floppy --fs-uuid --set=root 49d242fd-f885-4059-b7a4-4aac2e6cd9a9
if loadfont /share/grub/unicode.pf2 ; then
  set gfxmode=640x480
  load_video
  insmod gfxterm
fi
terminal_output gfxterm
