Did you try the ia64 early console options. See Documentation/ia64/serial.txt ... boot argument
you need to add on a rx2600 will look something like this:

console=uart,mmio,0xff5e0000

but the hex number will be whatever you need for ttyS3 (run "dmesg | grep tty" on your
kernel that does boot to find the right value).
