This looks like the patch which broke the driver in stable-2.6.32.y and
was later reverted by:


commit 2a96ae707525ef00a85bf374e56f0219c07eac5a
Author: Greg Kroah-Hartman <gregkh@...e.de>
Date:   Wed Jun 15 13:12:35 2011 -0700

    Revert "iwlagn: Support new 5000 microcode."
    
    This reverts commit 6f63415fc1b690cb50c2ad48ba6e9e6e88e271b4.
    
    It turns out this is not what we want to have happen for the .32 and
    .33-longterm kernels as it does not work properly at all.
    
    This was reported by Gentoo, Arch, and Canonical developers as causing
    problems for their users:
