FYI my configuration uses Buildroot toolchain/binutils 2.23.2/gcc-4.7.x

I have taken your branch and compiled it. I am testing like this:

sudo kvm -cdrom rootfs.iso9660

which works with upstream + the lscript patch

However, on your branch, the grub menu does not show up, I am only 
getting the grub minimal prompt. For the moment I cannot figure out why.

So that would mean that stage2 is OK but there is another extra issue.
