Unfortunately, I don't know the answer to this. I am booting from a
mirrored pool and storing most of my data on a raidz pool. (in part
because I thought raidz booting was not supported) I have never tried
to boot from a raidz pool in freebsd or with grub.
However, I note that booting from raidz is in the NEWS file for
grub2 2.00-7 (sid) but not 1.99-23 (squeeze), so I think that
trouble booting from raidz probably stems from grub, not from this
problem in zpool / libzfs.
To the original poster I'd suggest seeing whether grub2 2.00-7 from sid
enables booting from raidz...
