It turns out to be much more mundane, when repacking the kernel for use
in the installer initrd we don't include all modules (would be huge) and
we weren't including the crypto modules, yet sd_mod.ko has grown a
dependency on them.

Since I think my current workaround is going to succeed I have not yet
pushed the following, but we should plan to do so at some point I think.
I have tested it successfully in my local environment.

(nb: I'm about to post a series adding some Debian tests which require
changes to mg-debian-installer-update -- that would be a good juncture
to do this update I think)

Ian.

Subject: [PATCH] mg-debian-installer-update: Updates for newer armhf kernels
 from backports.

In newer kernels sd_mod.ko requires crypto symbols, so include
kernel/crypto/*.ko in the installer overlay cpio.

Also prefer the newest versions of packages pulled in from backports, by
reversing the sort. Anchor the linux-image package name to we only pick up the
-armmp flavour and not -armmp-lpae (which is unnecessary in an installer
environment).
