Interesting.  Are you aware that a new integrity target has been
developed and is approaching upstream inclussion?  It is called
dm-verity.

Mikulas posted the most recent version here:
http://www.redhat.com/archives/dm-devel/2012-March/msg00133.html

And here is the userspace setup code:

The original docs from Google's initial dm-verity are mostly applicable
(but need to be refreshed and included with the new version):
http://www.redhat.com/archives/dm-devel/2012-February/msg00119.html

dm-verity already has 2 formats, a 3rd could be added if you found the
existing formats somehow lacking, see:
http://www.redhat.com/archives/dm-devel/2012-March/msg00143.html
