There are patches from Doug Rabson which add support for booting
from
raidz/raidz2.

I tried it, but after a make obj && make depend the make failed with
different errors like undeclared and has no member named.
I used patch raidzboot-14052009.diff started patching from
/usr/src/sys/ , i'm not sure if this was the right way.
I'm also not sure if the way of installation was the right one,
here's the way i go:
gpart create -s GPT da0
gpart add -b 34 -s 128 -t freebsd-boot da0
gpart add -b 162 -s 5242880 -t freebsd-swap da0
gpart add -b 5243042 -s 11534141 -t freebsd-zfs da0
gpart bootcode -b /mnt2/boot/pmbr -p /mnt2/boot/gptzfsboot -i 1 da0
gpart bootcode -b /mnt2/boot/pmbr -p /mnt2/boot/gptzfsboot -i 1 da1
gpart bootcode -b /mnt2/boot/pmbr -p /mnt2/boot/gptzfsboot -i 1 da2
kldload /mnt2/boot/kernel/opensolaris.ko
kldload /mnt2/boot/kernel/zfs.ko
zpool create tank raidz da0p3 da1p1 d2p1
zfs create tank/tmp
zfs create tank/usr
zfs create tank/var
cd /dist/8.0-BETA3/base
export DESTDIR=/tank
./install.sh
You are about to extract the base distribution into /tank - are you
SURE
you want to do this over your installed system (y/n)? y
cd ../kernels
./install.sh generic
cd /tank/boot
cp -Rp GENERIC/* kernel/
cd /dist/8.0-BETA3/src
