Backported Kernel - install question

[Kailash Kalyani <listskailash@gmail.com>]

Hi,

I'm on Debian Stable with the default kernel:
$ aptitude search "~i linux-image"
i A linux-image-3.2.0-4-686-pae     - Linux 3.2 for modern PCs 

i   linux-image-686-pae             - Linux for modern PCs (meta-package)

I found that kernel 3.11 is available from wheezy-backports.
~$ aptitude --group-by=archive search linux-image-3.11
p   linux-image-3.11-0.bpo.2-486    - Linux 3.11 for older PCs 

p   linux-image-3.11-0.bpo.2-686-pa - Linux 3.11 for modern PCs 

p   linux-image-3.11-0.bpo.2-686-pa - Debugging symbols for Linux 
3.11-0.bpo.2-6
p   linux-image-3.11-0.bpo.2-amd64  - Linux 3.11 for 64-bit PCs 

p   linux-image-3.11-2-486          - Linux 3.11 for older PCs 

p   linux-image-3.11-2-686-pae      - Linux 3.11 for modern PCs 

p   linux-image-3.11-2-686-pae-dbg  - Debugging symbols for Linux 
3.11-2-686-pae
p   linux-image-3.11-2-amd64        - Linux 3.11 for 64-bit PCs


However, when I try to install it via synaptic, I found that there are 
broken dependencies:

My understanding is that it should be possible to install backports 
without breaking a stable install. What am I missing?

Sincerely,
