No, grub doesn't need to have anything mounted.  The sysimage mount and 
chroot is most useful to get access to your usual tools in their usual 
paths and to be able to edit the grub.conf file.  I've never tried to 
boot from a partition that far into the disk, though.   I had enough 
trouble back in the days when bios only knew 1024 cylinders that I've 
always put a small /boot partition as the first thing on the disk even 
though you shouldn't have to now.
