BTW, if you have some spare time and a desire to do some more testing, you can
try the following patch:
http://people.freebsd.org/~avg/zfs-spa-multi_vdev_root_support.diff

It adds support for multi-vdev root pool probing in kernel.
The best way to test is to remove zpool.cache before rebooting (but make sure to
keep a copy somewhere and be able to recover).  I'd use a boot environment (a
root filesystem clone) for this.

Thank you.
