Title:
  [Karmic] update-grub creates incorrect entry for FreeDOS

Status in grub2 package in Ubuntu:
  Expired

Bug description:
  After most recent update update-grub finally completes.  When I run it
  I see the following:

  roland at logikaldesktop:~$ sudo update-grub
  Generating grub.cfg ...
  Found linux image: /boot/vmlinuz-2.6.31-3-generic
  Found initrd image: /boot/initrd.img-2.6.31-3-generic
  Found memtest86+ image: /boot/memtest86+.bin
  Found FreeDOS on /dev/sdb1
  done

  The problem is it creates the following entry:

  ### BEGIN /etc/grub.d/30_os-prober ###
  menuentry "FreeDOS (on /dev/sdb1)" {
  	set root=(hd1,1)
  	search --no-floppy --fs-uuid --set 3137-16f9
  	drivemap -s (hd0) ${root}
  	chainloader +1
  }
  ### END /etc/grub.d/30_os-prober ###

  Neither Grub nor Karmic are seeing the SATA drives in the same order
  as the BIOS.  FreeDOS was installed on the first hard drive, which is
  a SATA 250.  The other two hard drives are SATA 1TB.  Both grub and
  Karmic are seeing the drives as 1TB, 250, 1TB.  Sorry, I don't have a
  different sized SATA to install so we can easily identify which drive
  Grub/Karmic are seeing first.

  The order is completely consistent.

  As a result of this discombobulation, FreeDOS cannot be booted.  It is
  trying to map the drives via the BIOS and the Grub mapping really
  hoses things.
