Don't include all the modules in the kernel, you only need those
necessary to access the boot partition, for example, i use the
following command to create core.img:

./grub-mkimage -d . -o core.img biosdisk iso9660 pc fat ntfs ext2 ufs
bsd boot ls multiboot

To create g2ldr, add the lnxboot.img header:

cat lnxboot.img core.img > g2ldr

This contain enough modules to do the test, no need to load extra
module from disk.

Also, please use linux to build grub2, *bsd may compile ok, but don't
know if the result is correct.
