With GRUB legacy, there are some limitations on /boot.  It cannot
be encrypted, cannot reside on some types of software RAID,
cannot be in an LVM logical volume, and must be in an ext2/3/4 
filesystem.  If your root filesystem violates any of that, then
you need a separate /boot partition.  GRUB 2 removes most of
those restrictions.
