OK, I think I can figure this stuff out. I'll likely build it into the
kernel as well, since there's no practical reason I can think of to make
aacraid a module (or the aic7xxx driver).
My question *now* is: How do I control the RAID level? How do I know
how the driver is treating the disks? How do I know if it's being
mirrored? etc. etc.
