Yes I think I need dmraid.  Looking at the Debian Installer FAQ there is
reference to using the installer Device Manager.  But I can not find where
I do this.  Does it mean to use LVM, or rather is that function available
from where I would be taken if I went down the LVM route from the
what to partition menu?

There was talk about dmraid as far back as November last year, and
someone (I forget who) talked about including a dmraid udeb.  But I
could not find any reference as to whether this had happened, or what
the planned timescale for its inclusion would be.

Reading the talk about dmraid I mentioned above there is support, you
just have to add in some extra parameters to grub (and there was a 
patch to include it).  I understand that Ubuntu have already tackled this.
