Switching to a phy: backend (a zfs zvol in this case) absolutely worked. I have to admit to trying it on a 2.6.40 kernel vs. 2.6.32 last time, so I'm changing multiple variables (I know, bad analysis!) but I don't have any reason to go back to 2.6.32 either. Everything is noticeably peppier too (not just disk - VNC, etc.).
