Welcome to Fedora 16 hell 8) Grub2 can handle this fine but it needs to be
told to do it via a map file which it won't do by default and which
preupgrade is apparently too dim to offer you as a choice.

I seem to remember grub-install or grub2-install docs contained the
relevant incantation to tell it STFU and do what it was told.
