Not really an answer to your question, I got a snapshot of the in 
development driver that seems to work just fine. I haven't run smartctl on 
the controller much mind you, as it seems to freak out my onboard controller 
too (AMD SB750). I could attempt it, but I've recently just switched over to 
that hardware for my main server, and I'm reluctant to try running smartctl 
on the array, as it'd probably require a reboot to get which ever disk back 
that might get dropped.

I might try it later, but I don't even have smartmontools installed.
