Heh, fun.

Well the problem appears to be that wpa_supplicant isn't getting started
by your distro any more. Unfortunately I'm not familiar with opensuse.
It seems it thinks the device isn't wireless but wired, since it starts
ifplugd. OTOH maybe it wants ifplugd for wireless too? It's possible in
theory.

I'm downloading a livecd to figure out what might be going wrong.

Can you try running wpa_supplicant manually to make sure it's a problem
in the distro/kernel interaction and not in wpa_supplicant/kernel?
