Does the kernel from here work for you?:

(As I've already said, this kernel works for our machine.)
How to reproduce this build? Have you published the corresponding rules?
I tried:
$ apt-get source linux-image-3.16.0-0.bpo.4-mckinley

(Parallellization, i.e., -j2, doesn't affect the result; I have checked
that.)

Yes, [this one] doesn't boot on our system. It might even be in our case a
strange/buggy behavior caused by old firmware for an otherwise correct

there is a difference between yours and ours machines:

It looks like ours has 2 Madison CPUs (if we are to trust this cpuinfo),
which are older than your Montecito ones.
[this one]:

So far, we've done a number of attempts to compile and boot a kernel (I'm
going to post the details and the kernels soon), and my conclusion so far is
that the only affecting factor is the version of gcc (even not -O1 vs
-Os/-O2).
gcc <= 4.5.3 produces a bootable kernel (as for
linux-image-3.2.0-4-mckinley, gcc 4.4.7 from wheezy and gcc 4.5.3 from
snapshots produced a bootable one in my experiments);
gcc > = 4.6.3 produces a non-bootable kernel.
So this already gives an initial hypothesis about the solution to 1):
To compile a bootable kernel for this machine, use gcc <= 4.5.3.
