It's working, thanks! Just one minor issue - the new core.img is confused about the root device: Welcome to GRUB! error: unknown device Entering into rescue mode... grub rescue> set prefix=(fd0,1,a)/boot/grub root=fd0,1,a grub rescue> That's qemu with one hard drive and no floppies.

Actually, GRUB 2 modules still confuse multiboot. Loading _bsd.mod or affs.mod would cause GRUB to hand. But "multiboot configfile.mod" actually crashed qemu 0.9.1 with "qemu: fatal: triple fault"! > however, it's still possible to load GRUB Legacy with my grubutil > package.
