Bug description:
  On the Oneiric testing system, I ran grub-install to reinstall grub
  for Debian Lenny.

  $ cat /etc/lsb-release
  DISTRIB_ID=Ubuntu
  DISTRIB_RELEASE=11.10
  DISTRIB_CODENAME=oneiric
  DISTRIB_DESCRIPTION="Ubuntu oneiric (development branch)"

  The version of grub:
  $  dpkg -l |grep grub
  ii  grub                            0.97-29ubuntu62                         GRand Unified Bootloader (Legacy version)
  ii  grub-common                     1.99-11ubuntu1                          GRand Unified Bootloader (common files)

  
  Debian Lenny is on /dev/sda:
  $ parted -s /dev/sda print
  Model: ATA VMware Virtual I (scsi)
  Disk /dev/sda: 17.2GB
  Sector size (logical/physical): 512B/512B
  Partition Table: msdos

  The root partition of Debian Lenny is /dev/sda1, therefore:
  1. mount /dev/sda1 /mnt/
  2. ls -alFd /mnt/boot/grub/
  drwxr-xr-x 2 root root 1024 2011-08-31 03:12 /mnt/boot/grub/

  After downgrading to the grub version on Natty, i.e. grub_0.97-29ubuntu61, it works:
  $ dpkg -i grub_0.97-29ubuntu61_i386.deb
