If you're using the serial console, you'll need a null modem cable between the two machines. Then you boot with console=ttyS0,115200 on the node you're testing and run "screen -L /dev/ttyS0 115200" on the other. Change ttyS0 to whatever is appropriate for each node.

Putting it at the end will make it the "primary" console so kernel messages should automatically be directed there. When your system crashes, the messages will be preserved in the screen session on the other machine.

The other option is netconsole, but the modules for that aren't on the install initrd.
