I agree. That's what I would have done also.

I see it didn't work.
Looking at grub-mkimage --help, another thing to try is running:
/usr/bin/grub-mkimage -d /usr/lib/grub/i386-pc -O i386-pc \
--output=/boot/grub/i386-pc/core.img biosdisk ext2 part_msdos
This omits --prefix and defaults to /boot/grub.
Another option to try is just --prefix=/grub
In any case, this command should just create core.img.
You don't mention what the following line translates to:
$grub_setup" ${allow_floppy} ${setup_verbose} ${setup_force} \
--directory="${grubdir}/${grub_modinfo_target_cpu}-$grub_modinfo_platform"\
--device-map="${device_map}" "${install_device}"
Id think it would be
/usr/sbin/grub-bios-setup --verbose --directory=/boot/grub/i386-pc \
dev/sda
Another thing to try is top manually create /boot/grub/device.map.
echo "(hd0) /dev/sda" > /boot/grub/device.map
That's a tab between the entries.
If you still can't get it to work, the next step is to dig into the
source of grub-bios-setup. I can help with that.
