I would have thought so too.  Regardless of that, I bet this is fake 
RAID.  Did you intentionally choose to go this route?  In most cases 
you are better off using the md driver.  For example, with a fake RAID 
system, if the motherboard dies you may have difficultly when moving 
the disks to another system.  The disk data is typically stored in a 
vendor-dependent format.

Of course I'm probably telling you stuff you already know.
