I see! Well, it's apparently made it to into Jaunty, so that's good news. :)

I'll see what I can gather. Just for reference (in case it's been 
missed) the checksum I receive (0xBAF vs. 0x805) and the checksum 'ml' 
received (0xF36 vs. 0x805) are different. Presumably it's just the table 
format, and not the contained metadata that is checksum'd?

The RAID card is perfectly happy with the array. It's rather bizarre. I 
may see if I can install Windows on it when I have some time.
