Of course a driver gets loaded, otherwise you wouldn't see the disks at all :)

It's just that the open source driver doesn't seem to support the fakeRAID 
functionality of the closed source driver

With a real hardware RAID that wouldn't be a concern. With real hardware RAID, 
the controller only shows one disk, and the OS never has an option of anything 
else
