Ah seems like it was too late for me yesterday.
the Replaces/Conflicts in grub-pc, only tell dpkg/apt that they're
allowed to automatically remove grub-legacy when installing it.
Though it seems aptitude honours it the other way too, If you want to
install grub-legacy it marks grub-pc automatically for removing.
