the next best thing to having a serial port is to edit
/etc/rsyslog.conf, and change the destination of all the logs from
/var/log to somewhere nonvolatile, like /home/olpc/log (be sure
to create the directory).  then either reboot, or "killall -HUP
rsyslogd" to make the config change take effect.  this might give
some information on what was going on before the hang.
