Make sure you have an 'insmod' for the file system, i.e. UFS or ZFS. I think chainloader is wrong. From the GRUB2 manual I see this as the FreeBSD example, and honestly if that doesn't work I'd go subscribe to and post on help-grub at gnu.org. I'm not sure how many FreeBSD + GRUB2 experts you'll find on here. 

You aren't making these edits directly to grub.cfg are you? But the scripts in /etc/grub.d and then running grub2-mkconfig after each change right?


     menuentry "FreeBSD" {
               insmod zfs
               search --set=root --label freepool --hint hd0,msdos7
               kfreebsd /freebsd@/boot/kernel/kernel
               kfreebsd_module_elf /freebsd@/boot/kernel/opensolaris.ko
               kfreebsd_module_elf /freebsd@/boot/kernel/zfs.ko
               kfreebsd_module /freebsd@/boot/zfs/zpool.cache type=/boot/zfs/zpool.cache
               set kFreeBSD.vfs.root.mountfrom=zfs:freepool/freebsd
               set kFreeBSD.hw.psm.synaptics_support=1
