All I can think of is virtualbox, but I'm almost certain I did not have
virtualbox loaded (i.e. modules disabled so they wouldn't load) for my first
test with wired ethernet (yes, I know that virtualbox modules are known 
for causing problems).

Ah, yes, I had another out of tree module:
http://www.thinkwiki.org/wiki/Tp_smapi
(on thinkpad W500)

Module                  Size  Used by
hdaps                  13616  1 
tp_smapi               23531  0 
thinkpad_ec            12857  2 hdaps,tp_smapi

So, I suppose the next step is to reproduce without those modules loaded,
which I'll do next.

Thanks,
Marc
