As these are all at KERN_ERR, surley you can set the console down to
KERN_EMERG only and these will all be suppressed ?  Are you already
using loglevel=0 or just quiet.  In our main kernels we have the commit
below pulling the loglevel lower by default:

  commit 8464b5966d404505aa506c33c1099e6e507cdfc7
  Author: Tim Gardner <tim.gardner at canonical.com>
  Date:   Thu Oct 8 11:42:36 2009 -0600

    UBUNTU: SAUCE: (no-up) raise the default console 'quiet' level to 2

I don't see this in the n7 kernel, might that help?  We could even move
it lower if appropriate.
