 message after reboot

 I read the thread Andy pointed to us ( http://lkml.org/lkml/2009/1/21/250
 ). This is a feature that will help many people but I don't think we have
 the manpower to think of upstream for this right now. Thus I guess I can
 modify your patch and send it. We could have a boot parameter
 (om_ramconsole=N) and we could use 2^N for the ramconsole size. It would
 be disabled by default. Since we would have to enable it manually and we
 would provide the documentation concern #1 and concern #2 are not really a
 problem.
