Recompile IrDA driver with debugging information (see below)

Probably it's not bad but having serial driver compiled in the kernel is 
pointless IMVHO because R31 doesn't have any external RS232 port. Or have you 
hacked it to have one? ;) (I would assume there is a connector on mainboard 
but IBM decided to cripple the notebook.)

Nope, mine looks like this:
crw-rw----    1 root     dialout    4,  64 2002-06-20 00:13 /dev/ttyS0
crw-rw----    1 root     dialout    4,  65 2002-06-20 00:13 /dev/ttyS1

OK. Step by step instruction:

1. Patch the kernel with the patch attached in the previous post
2. Compile with the following options:

#
# IrDA (infrared) support
#
CONFIG_IRDA=m
CONFIG_IRLAN=m
# CONFIG_IRNET is not set
CONFIG_IRCOMM=m
CONFIG_IRDA_ULTRA=y
CONFIG_IRDA_CACHE_LAST_LSAP=y
CONFIG_IRDA_FAST_RR=y
CONFIG_IRDA_DEBUG=y # <- ! This one is important !

#
# Infrared-port device drivers
#
CONFIG_IRTTY_SIR=m
CONFIG_IRPORT_SIR=m
# CONFIG_DONGLE is not set
CONFIG_USB_IRDA=m
CONFIG_NSC_FIR=m
# CONFIG_WINBOND_FIR is not set
# CONFIG_TOSHIBA_OLD is not set
# CONFIG_TOSHIBA_FIR is not set
# CONFIG_SMC_IRCC_FIR is not set
# CONFIG_ALI_FIR is not set
# CONFIG_VLSI_FIR is not setCONFIG_SERIAL=m 

CONFIG_SERIAL=m # <- ! This one also

3. After rebooting with the new kernel disable serial ports:

setserial /dev/ttyS0 uart none
setserial /dev/ttyS1 uart none

and remove serial module altogether:

rmmod serial

4. Try to load nsc-ircc with the following parameters:

modprobe nsc-ircc irq=3 dma=3 io=0x2f8 dongle_id=0x09

If it does not load report what do you have in /var/log/kernlog (should give 
some clue what is going on)

Have you got TV-out working?
