I believe I patched dmraid to not create the dev nodes in /dev/mapper, but just in /dev instead. This should fix the problem with the lvm boot script. I also have been working with a user trying to install edgy using this package and it sounds like the installer thinks they are lvm volumes and chokes, so hopefully this will fix that as well.
