[ltp] IrDA on a T42p?

I'll skip the long story. I have an old Palm Pilot that I want to send
a program to. The 42p doesn't have a serial port and I can't make the
USB/Serial connector talk to the Palm (it talks to my Garmin GPS just
fine). So I thought I'd use IrDA.

I installed the IrDA tools and I now see this in dmesg:

That doesn't look good :-). Anyone got it working? Pointers, etc.,
appreciated.

                                        Be seeing you,
