title Gentoo Linux 2.6.31-r10

kernel /boot/kernel-2.6.31-gentoo-r10 root=/dev/sda5

title Gentoo Linux 2.6.31-r10 -- genkernel
root (hd0,0)
kernel /boot/kernel-genkernel-x86-2.6.31-gentoo-r10 root=/dev/ram0 init=/linuxrc 
ramdisk=8192 real_root=/dev/sda5
initrd /boot/initramfs-genkernel-x86-2.6.31-gentoo-r10

The first entry is for the manual configuration, while the second one is for the 
kernel generated by genkernel.

Thanks,
