Have you considered moving to 10/08 ? ZFS resilver performance is much improved in this release, and I suspect that code might help you.
You can easily test upgrading with Live Upgrade. I did the transition using LU and was very happy with the results. For example, I added a disk to a mirror and resilvering the new disk took about 6 min for almost 300GB, IIRC.
