Infrared broken on tibook

[John Goerzen <jgoerzen@complete.org>]

Hi,

I have a 400MHz tibook and I'm trying to get infrared going.

On bootup, dmesg shows this when macserial.o is loaded:

macserial: i2c-modem detected, id: 1
PowerMac Z8530 serial driver version 2.0
tty00 at 0xd9867020 (irq = 22) is a Z8530 ESCC (internal modem)
tty01 at 0xd986e000 (irq = 23) is a Z8530 ESCC (IrDA)
i2c-core.o: i2c core module

So, I assume that /dev/ttyS1 is the SIR interface.  Strangely:

# cat /dev/ttyS1
cat: /dev/ttyS1: Input/output error

Obviously, irattach therefore fails.

I am running the latest 2.4.20 from benh.
