You can specify multiple console= options on the kernel command line.
You will need to create a new device to use /dev/console. The official
/dev/console is now character device 5,1.
+(You can also use a network device as a console. See
+Documentation/networking/netconsole.txt for information on that.)

Here's an example that will use /dev/ttyS1 (COM2) as the console.
