The first statement is a bit confusing to me. Whenever linux-backports-modules-wireless gets installed in Lucid, the wireless drivers from that (which are currently around 2.6.33 level) are used, regardless which kernel is installed. So I would somehow expect when l-b-m is installed, then 2.6.33 should work the same.

Christian's regression seems to be between 2.6.31.(probably .9 as stable .12 only now went into proposed) and 2.6.32.9 (Ubuntu-2.6.32-16.25). Michael's regression I don't know for reasons above.

Maybe two things to try:

1. as root: echo "options iwlagn disable_hw_scan=1" >/etc/modprobe.d/iwlagn.conf
Then reboot and see whether this makes things better or worse.

2. Try to narrow the point of regression: http://kernel.ubuntu.com/~kernel-ppa/mainline/ contains prebuild mainline kernel
v2.6.32-rc? are after 2.6.31 but before 2.6.32. Or 2.6.33-rc? come before 2.6.33. (l-b-m-w should have no impact here).
Unfortunately this still will be slightly coarse as rc1 and rc2 usually have the biggest changes to drivers.
