No, it doesn't.

It says:

]  Once you've hooked the cable up you should add 'console=ttyS0,115200 
]  console=tty0' to the command-line of the debuggee. This causes all 
]  console message to be sent to ttyS0 as well as well as the standard 
]  console. The last console= parameter determines where the console input 
]  should be handled from; so if you want to use the serial console to 
]  accept input also you'll have to exchange those parameters.

AFAIK, that will dump tty0 to the serial port and the other machine. What 
needs to be dumped is all kernel messages, not the console number zero.

I'm not working on tty0, I'm on X, anyways. I need to know if there are 
kernel messages, those will not go to tty0. I need everything that klogd 
gets. As a continuous dmesg.
