can you try the chainload ?
Finally I chainloade Mandriva and FreeBSD， it works fine .

edit the file /etc/grub.d/40_custom , this is my
configuration(https://gist.github.com/954772) :

#!/bin/sh
exec tail -n +3 $0

menuentry "Mandriva 2010 2 ChainLoader" {
	set root=(hd0,12)
	chainloader +1
}

menuentry "FreeBSD8.2 Chainloader" {
	insmod ufs2
	set root=(hd0,3)
	chainloader +1
}
