This patch is going to break our userspace parsing scripts if you change 
the output format.  Admittedly, we're probably one of the few users who 
actually parses this output, but we do have reasons to do it for our 
firmware.  If there was some improvement being introduced here, we'd 
happily handle multiple regexs (we constantly add new patterns when new 
kernels are released), but I'm not seeing how this is better.
