Hi Ben, somehow netconsole doesn't do anything for me. But it turned out the the system behaviour is not exactly reproducible and anyway I can see the messages on screen if X is not started (because nvidia module banned ;-) ).
So, here I have the following error message, hope that helps! Best regards, Andreas.
