I confirm you that using current GIT head as a base (commit 
dd430afbf874f6212742c079d72b4b9e959e0542) my steps for making 
two-dimensional hybrid disk (Both CDROM / Harddisk and BIOS / EFI) seem 
to work ok.

So I confirm that you have succesfully fixed the problem about grub 
rescue not finding grub device which the OP reported.

I paste here my steps here again (I know the steps can be improved).

How do I build and prepare my system
------------------------------------
Make sure no Debian grub package is found in chroot

apt-get remove '.grub.'
Grub2 (efi+pc)) Build and installation

# Make sure we are testing the right revision
mkdir grub_upstream
cd grub_upstream
git clone git://git.savannah.gnu.org/grub.git .
git checkout COMMIT-TO-TEST
# Remove any non git related file - BEGIN
git reset --hard
git clean -f -d
git clean -f -x -d

# Remove any non git related file - END
# Build efi based grub and install it - BEGIN
./autogen.sh && ./configure --enable-grub-mkfont --with-platform=efi && make
# Dont forget to delete any rest of previous installation - BEGIN
sudo rm -rf /usr/local/etc/grub.d/ /usr/local/bin/grub-* 
/usr/local/share/grub/
# Dont forget to delete any rest of previous installation - END
sudo make install
# Build efi based grub and install it - END
make clean # Prepare for next build
./configure --enable-grub-mkfont --with-platform=pc && make # Prepare 
for a i386 build
sudo make install # Install i386 build

Super Grub2 Disk build
----------------------
sudo grub-mkrescue --output=/tmp/test1.iso
