Maybe making dmesg not restart from scratch on reboot for all machines
would help here? On some systems (Solaris/sparc, i think even
NetBSD/sparc), i can see old messages after reboot/panic. I think this is
implemented by using the last page of memory for the dmesg buffer, and
unless this memory is cleaned out on reboot, the information should be
preserved (I don't know what die BIOS' memory test does there...).
