Ok, here's what we'll need to know in order to fix this:

 - Does a current (3.x.y) kernel reproduce the same trouble?  If not,
   we can try some intermediate versions from snapshot.debian.org to
   try to find the fix and apply it to squeeze.

   The only packages from outside squeeze that should be needed to test
   this are the kernel image itself, linux-base, and initramfs-tools.

 - Unfortunately there have been some iwlwifi fixes recently upstream,
   so if a 3.1.y kernel reproduces trouble, you should also try a kernel
   from the 3.2 series before reporting it upstream.  These versions
   should appear in experimental sooner or later, or if you have time to
   build from source following the instructions from [1], that's even
   better.

 - In any event, full output from "dmesg" (as an attachment) after
   booting up with the most recent kernel you're able to test and
   reproducing the problem would be useful.

Thanks and hope that helps,
Jonathan
