So it doesn't report an error here, correct?

OK, this probably means that you have the default serial driver
installed and it claims the device. The setserial is needed in order to
release the port again. You might want to try to have the default
serial driver not touch the IrDA port at all -- the simplest thing
would be to try running without serial plug support for the start.

This seems to indicate that you're trying to use /dev/ttyS2. But as
you're not using the serial port IrDA driver but an extended FIR driver
the device is probably "irda0" (and it doesn't have a path, as it's a
network device). Try "ifconfig -a", it should be listed. I don't have
IrDA on my current machine, so I can't tell what exact configuration
setting must be changed from "/dev/ttyS2" to "irda0". Start with this,
first.

As I said, try modprobing after the "setserial" call or even omit
serial support in the kernel.
