If you want to change what Linux thinks the base address of one of your 
serial ports is, you can use the setserial command, like this:

setserial /dev/ttyS3 port 0x2E8 irq 3

The "uart" and "autoconfig" parameters might be interesting to you also.

As for what file you modify... Depends on your Linux distribution. Mine is 
called /sbin/init.d/serial.
