[gentoo-user] Installing Gentoo: Grub, alternate GNU/Linux system on another partition

I'm giving Gentoo another try, having been using Ubuntu for quite a while,
and more recently Mint.  I would like to be able to access Mint until the
Gentoo system is working as I'd like it.

I have gotten through the install, for the most part, up to grub.  I can
see how to edit the grub.conf file for my Gentoo partition.  However, it
isn't clear to me from the examples how to write a grub.conf entry for
Mint's root (/) partition, on /dev/sda8. I am asking for advice on writing
the grub.conf file.

 Here are the various partitions involved:

    Gentoo:
       /boot      /dev/sda1
       /            /dev/sda2

   Mint    (/boot is not separate)
       /           /dev/sda8

The Mint kernel is using an initramfs, while I have manually configured the
kernel on Gentoo, at least for now.

Grub 2 is not transparent to me.  The kernel is:

    /boot/vmlinuz-3.0.0-13-generic

the initrd-img file is:

   /boot/initrd.img-3.0.0-13-generic

My grub.conf file for gentoo would look like this:

###########
default 0
timeout 30
#splashimage=(hd0,0)/boot/grub/splash.xpm.gz


title Gentoo Original
root (hd0,0)
kernel /boot/kernel-3.0.6-gentoo-r1 root=/dev/sda2
###########


I have a few other questions of a more or less minor nature.  Perhaps
better to ask them separately.
