It's on my list to review, test, merge and release. Unfortunately my
new machine which Intel Matrix Raid capable, had a few teething
problem when it arrived resulting in me testing alternative CPU and
eventually singling out broken PSU. Thus I was late in getting the
machine available to push this.

I'm highly interested in these patches and now I was about to prepare
/ push personal branches to d-i/partman repos with this functionality
among other fixes targetting jessie.

Timing wise, it was late to review by me for wheezy. Although mdadm is
far supperiour and preffered over dmraid, one can setup Intel Matrix
Raid using intel's bios firmware & then one can activate those volumes
and perform complete installation. But indeed more flexibility would
be a first out of any operating systems/distros out there.

I apologies and I am expecting to review and merge your work shortly
after wheezy release. (well actually last week of may / early june.
Because before that I'll be busy with boost transition).
And we can always push out an unofficial intel matrix storage
installer image for wheezy later =) as a technology preview ;-)
