I wish I could use it on PowerPC to work around the "claim failed"
problem, but I'll still need to link "memdisk" and "cpio" with
grub-mkimage.

I have a patch for PowerPC, but I think I'll hold it until your patch is
committed.  I could change my patch to be more in-sync with i386, in
particular use /boot/grub as the blessed directory.

Actually, if biosdisk is a part of the core image, other modules are
preloaded.  I don't quite understand the mechanism.  I think it should
be OK for now.  Then we can refine the loading and the initialization.
