I read it as such. Remember, our bootloader doesn't really understand
raidframe; we're cheating. It only knows an additional offset, which 
happens (well, we did it un porpose) to be where a raid0 root partition
is inside the raid disk's image on both (all) the component disks in
a raid0 setup.

As a consequence, the individual boot disks aren't hidden from the
kernel.
