You need to have CONFIG_MAC_SERIAL=y and CONFIG_SERIAL=n in your
kernel config.  On my Pismo, this results in

  PowerMac Z8530 serial driver version 2.0
  tty00 at 0xc98c9020 (irq = 22) is a Z8530 ESCC (cobalt modem)
  tty01 at 0xc98d0000 (irq = 23) is a Z8530 ESCC (IrDA)

in dmesg output.  The modem is then accessible via /dev/ttyS0, while
the IrDA port is at /dev/ttyS1.
