The solution on recent Sequent SMP systems was to add a daemon that takes
the equivalent of the printk()'s and buffers them.  That way the console
(which is *always* a vt220 with a max baud of 19200)  doesn't hold back
the kernel.  You get an extra process with it's own thread of execution
doing the buffering.

Could an existing daemon (syslogd?) be modified to do this buffering?
