I tested out a daily build, and was unable to replicate the problem, so I then upgraded my kernel to 3.11.0-13, and again did not see the problem.
I think we can safely say that whatever the issue was, it is no longer worth pursuing. Thanks for your help!

I upgraded kubuntu 12.10 to 13.04 last night, and observed the update- initramfs bug (https://bugs.launchpad.net/ubuntu/+source/kmod/+bug/1073062). Upon restart, KDE loads, but NetworkManager takes 100% cpu, and fails to allow wireless connections. (Changing the backend from NetworkManager to Wicd does not help.) However, if you restart and select the 3.5 kernel instead of 3.7 kernel, the problem disappears completely. I'm happy to help debug and provide further information if you can tell me what it is that's needed.
