Did you see a warning/error from the grub-install run in the postinst
that it couldn't embed core.img?
Please try if with 1.97-1 running grub-install --force yourself fixes
this.
We didn't change anything in the first stage bootcode, so this is
probable because the core.img on the disk has changed the position but
the MBR wasn't updated.
