MAybe booting with multiboot in 32-bit mode would be a better idea? If you need to do some specific tasks before switching to 32-bit mode speak about it - adding them to multiboot may be useful. >Is there any way to have grub do this (legacy or grub2)? I tried chainloading, but I think that may be loading it in 32-bit mode. Any pointers on what code I would have to modify to >create that option for grub? chainloading loads in realmode, even the A20 bug is reenabled if possible. But I discourage usage of it.
