Difference between linux-image-3.2.0-0.bpo.1-amd64 linux-image-3.2.0-0.bpo.2-amd64

[SANCHEZ Jeremy <mailingdebian@debian2.ath.cx>]

Hi,

I have a question about a kernel backports, I want to install them on my 
company's server... But I have a choice between bpo1 and bpo2.
I have check, and I see no difference except the kernel version...
But I see about the updates, it's more frequent for the bpo2.....

Does someone can me explain the difference please?

I think bpo2 is updated for integrate new or recent firmware or other, 
but It's possible I'm wrong....:s

Thanks

Jeremy
