                                                                    ^^^^^^^
                                                         should be: (hd0,0)

Good question.  Do you have a separate /boot partition?  Where is it?
This configuration indicates that its the first partition on /dev/hdb,
which seems odd, since your / is on /dev/hda6.  For instance, if your
/boot is on /dev/hda5, the root line should be (hd0,4).
