My grokking of the code confirms that the vdev labels of a detached
vdev are wiped. The vdev label contains the uber block. Without the
uber block, we can't access the rest of the zpool/zfs data on the
detached vdev.
On a related note: I've been itching to make what you want possible
also (ie detaching a vdev from a mirror and getting a zpool from via
zpool import. I'll see what I can do over the next few weeks. I
presume you would be willing to be a tester? ;)
