will sabayon dual boot with suse 11.3
 

Thinking of putting sab alongside suze 11.3, I wonder if the bootloaders are compatible (versions of grub) or if only native systems (apart from windows/apple) are acceptable.

I have both installed on a DVD booting with Grub Legacy. Sabayon has all the boot files for Grub Legacy and Grub2 which you can see if you boot the Live CD. I don't have Sabayon on a hard drive. Opensuse will usually install its bootloader to the mbr unless you go through a few extra steps in the bootloader install process so you might be better off installing Sabayon first. On the other hand, I really don't know whether Sabayon on a hard drive uses Grub Legacy or Grub2. It's not that hard to boot Grub2 from Grub Legacy.
