OK, this is telling you that ttyS2 is not the correct COM port for your irda 
device.  However, looking at your dmesg there's only two serial ports 
reported, so ttS2 is not defined:
===========================================
serio: i8042 AUX port at 0x60,0x64 irq 12
serio: i8042 KBD port at 0x60,0x64 irq 1
===========================================
You need to enable some virtual (COM) ports.  In your kernel configuration you 
will need to set additional serial ports.  Go to:

Device drivers --> Character devices --> Serial Drivers -->

and either enter a number higher than just 4 under:

 (4)  Maximum number of 8250/16550 serial ports
 (4)  Number of 8250/16550 serial ports to register at runtime

or better, on the latest stable kernel select:

 [*]  Extended 8250/16550 serial driver options
 [*]    Support more than 4 legacy serial ports
 [*]    Support for sharing serial interrupts

If when you reboot you keep getting the same error then you need to try 
different ttySx number, where x is 0,1,2,3,4, . . .  Note that some numbers 
could cause IRQ conflicts and could crash your machine.  In that case reboot 
and try again.

Unless the COM port has been set correctly for your irda any module selection 
will fail.

Ditto.

OK, it would be really strange if an irda chip of your type was detected just 
out of thin air without COM ports set in the kernel.  Thankfully, it isn't.

Some old laptops are even more problematic . . .
