For the record, Marek and I (and Sean) had talked a bit on IRC.  These
messages being log_xxx() and not dev_xx() instead make the more
functionally useful as dev_xxx() converts to printf() and messes with
the timing.  log_xxx() puts them in the buffer and will not break the
timing.  Marek objects to the fundamentals that dev_xxx() does not
function like it does in Linux (and please correct me if you feel I'm
mis-representing your views).  This could be solved by plumbing
dev_xxx() to use log_xxx() if LOG is enabled automagically.  I don't see
transitions like that as blocking for this patch, Marek does.
