If you only cared about crash dumps you could just always use re-draw
behaviour, disable Xen output after console_endboot(), but always
*re-enable* output, at coordinate (0,0) top-left of screen, on any call to
start_sync_console(). That usually indicates something important is being
printed. :-) Starting at top-left means you do not obliterate the most
recent dom0 output.
Would that be acceptable?
