Doh!  Make that
    setserial /dev/ttyS2 irq 7

But as I just said, I advise you *not* to use irq 7 for the
IR port.  Disable the serial port (tpctl --rs1=dis) and use
irq 4 for the IR port (tpctl --rs2=irq4 --rs2=0x3f8 --rs2=ena ;
setserial /dev/ttyS0 auto_irq autoconfig) instead.

Someone please let me know if they have successfully used
irq 7 for anything but the parallel port.
