A quick look on http://www.linux-laptop.net/ reveals three pages for the
A22M, one of which (http://mobilix.org/ibm_a22m_e.html) might be
interesting to you:
I had only time for a quick check. Enable IrDA in the BIOS. SIR works on
/dev/ttyS1. irdadump detects my HP Laserjet 2100.
FIR module nsc-ircc doesn't load correctly. Please read docs for special
settings in /etc/modules.conf. "
So, ok, Fast Infrared (FIR) maybe doesn't work, but you should be able to get
normal infrared (SIR) working.
I don't have your machine, but maybe I can give you some advice

This seems ok. to me. (It seems that you made the "irattach" correctly.)

You need nsc-ircc if you want FIR, but according to the web page above,
it seems to have problems. You better test SIR first, and when you
succeed, try FIR.

irattach /dev/ttyS3 -s 1
and it works (yours should be ttyS1). The utility "irdadump" from the
irda-utils package, should show if there is any activity in the irda
If you have another Laptop with linux, you can try to make a PPP
connection between them for testing purpouses. On one machine:
pppd /dev/ircomm0 188.8.131.52:184.108.40.206 noauth
on the other machine
pppd /dev/ircomm0 noauth
and you should be able to ping one another (or ssh, or whatever).
hope this helps.
