Thanks to your pointer, I have verified that the Thinkpad 600 is
indeed one of those models for which the IrDA interface appears as a
normal serial port.  

IBM provides DOS and NT configuration programs which enable/disable
the actual serial port on the box, as well as the IrDA port.  I've
downloaded the NT version of this program, and run it successfully; I
disabled the serial port and enabled the IrDA interface.  

During boot I get a message from dmesg like so:

  com0 at isa0 port 0x3f8-0x3ff irq 4: ns16550a, working fifo

I assume that this maps to /dev/tty00.  Unfortunately, when I try
pilot-xfer /dev/tty00 --list, and then try to sync, it just hangs.
:-(
