Are you running update-grub2 after editing the files? See below for the
files I changed.

I struck that also using grub2-splashimages. The fix is to edit
/etc/grub.d/00_header:

...

case ${platform}:${GRUB_TERMINAL} in
pc:gfxterm)
# Make the font accessible
prepare_grub_to_access_device `${grub_probe} --target=device
${GRUB_FONT_PATH}`
cat << EOF
if font `make_system_path_relative_to_its_root ${GRUB_FONT_PATH}` ; then
set gfxmode=640x480
insmod gfxterm
insmod vbe
terminal gfxterm
fi

...

See where "set gfxmode=640x480", that allows the menu to be 640x480
(which the grub2-splashimages mentions in
/usr/share/doc/grub2-splashimages/README) while setting:

GRUB_CMDLINE_LINUX=vga=791

in /etc/default/grub allows the kernel to boot in the higher res.


This is on Lenny and everything is working fine.
Looks like a bug in /usr/share/doc/grub2-splashimages/README where it
says to run update-grub, that should be update-grub2.

Arrrgh ... I see that:

fischer:~# less /usr/sbin/update-grub2
#!/bin/sh -e
exec update-grub


Sorry about the noise.
