No one has written the code to make it do so? :)  (The code right now
enforces the condition that the used part of all components is the same size.
This requirement would have to change, for a start.  Then one would just need
to put together a file similar to src/sys/dev/raidframe/rf_raid0.c to handle
the slightly different mapping.  A little bit of glue in a few other places, 
and it should 'just work' :)  )

:) I'm happy to hear someone say that :)
