I think you have a similar box to mine, which uses an ALi south bridge
for serial.

The problem is that you can't have both serial (sio) ports running at
the same time otherwise you might lock up your box.

Try adding:
hint.sio.1.at="isa"
hint.sio.1.port="0x2E8"
hint.sio.1.irq="4"

to your /boot/device.hints files (you may have to staticly link the
hints, I used this with a kld sio driver).

Now, these MAY need to be changed.  To get the correct information,
you need to run ofwdmp -ap, and look at the output.  Search for serial.
You should see something similar to:
        Node 0xf00782f8: serial
          port-a-ignore-cd:
          interrupt-priorities:
            00 00 00 0c 00 00 00 0c
          reg:
            00 00 00 00 00 00 03 f8 00 00 00 08

if you see the port-a-ignore-cd, this will be the first port, or your
console, find the next serial entery, and that should have
port-b-ignore-cd, and that is your second serial port.

The address in the reg which looks like PC io port is what you want.
(notice the 3f8 in the reg dump above).  There should also be an
interrupts property, that is the interrupt that you need to attach.

Be careful, on the sparcs, they don't like interrupts >7 on the isa
bus!

If you can't get this to work, send me a copy of your "ofwdump -ap"
command, and I can help you more.

Good Luck.
