Regarding your built kernel with the reverted patches: my bad for not installing the linux-image-extra-* package. I did not realize the wireless drivers resided there.
I can now report that the upstream fix mentioned in the previous comment #13 resolved the issue for me, and I am able to connect to WPA-EAP enterprise network using latest 3.8.0-24 kernel.
