Just to piggyback, I've been experiencing similar problems with my new X40
trying to get the IrDA to work at all. I've tried several sets of instructions
(sorry, details on which at home) without success. I get the same error message
as you. One of these sets included a small patch to the nsc_ircc module, but
the result was the same.

What I'm currently working on is re-compiling the kernel (2.6.10) with serial
support as module, since I've seen a few references that the IrDA won't work if
the serial support is compiled in. (I have tried the setserial command line
quoted above.)

Anyway, please let me know if you get yours working, because maybe the solution
will be the same :).
