Did a quick test and this is how i installed it:
sudo apt-get install syslinux sbm
sudo cp /usr/lib/syslinux/memdisk /boot/
sudo vim /boot/grub/menu.lst

And adding this entry. Remember to change (hd0,4) to your root.
title           Smart Boot Manager
root            (hd0,4)
kernel          /boot/memdisk
initrd          /boot/sbm.img
boot

Grub is starting fine and choosing SBM give me a new menu with several
devices to boot from but i don't see my DVD. I think i could be that
SBM cant boot from a SATA DVD.
