The other problem is that the "scrollback buffer" is initialized from screen contents when syscons starts up properly. If you boot in -v mode you can *easily* get two or three screenfulls of data scrolled off the top of the screen before sc0 probes and attaches. You can have a 1 million line "history" but it still won't recover those 3 lost screens of data. Only dmesg(8)/sysctl can get to it.
