interesting problem, and hasn't been fully solved yet. Currently I connect the serial port to a box with a lot of serial ports, and that box is network accessible.
Do you know if there is an KVM switch equivalent for serial port ?? How do you monitor multiple LinuxBIOS boxes except using many minicom ??
You get a terminal server such as a Cyclades:

The nice thing about a serial port is that it is realistic to always log everything even from a large amount of machines. So it's quite possible to build a central monitoring application that automatically records oopses that appear on an serial console and forward them to the system administrator, and with the logs the system administrator could see what actions led up to the oops.
How do you connect these 350 nodes "physically" to you console ?? Do you need many consoles or is there any think like "hub" the LAN ??
With 32-port terminal servers thats just a dozen of them.
