A new long report :-)
Setup is the same as last time --
* TP 600E, findchip Found NSC PC87338
* kernel 2.2.18, unpatched except for Thomas Hood's nsc-ircc patch
minus the request-region chunk.
* irda-utils-0.9.13
* tpctl 1.0
* pcmcia 3.1.24 (for lspnp/setpnp)
I looks as if irtty might have been responsible for my failure last
time. This time I was able to load the module, irattach to it,
and irdadump did see some traffic on the link (although very little --
only one packet every five seconds or so), but the Palm gave no
indication of seeing any traffic, and it did not appear in the discovery
log.
((Maybe I am asking for the impossible now? Is the Palm FIR-capable?))
Anyway, here's the log, captured with 'script' and edited for clarity.

At the end, the serial port again claims to have an 8250 uart, (which is
what it did when I crashed last), so I proceeded to take the machine
down to runlevel 1, umount /home and /usr, disable and then reenable the
IR port using tpctl (no crashes this time!), reload the serial module
(this time it recognised the uart as a 16550A), and bring the machine
back to runlevel 3, and remount the partitions. No reboot this time :-)
I'm not sure whether this is a success or a failure. I could load
nsc-ircc, irattach irda0, unload the module and restore the IR port, but
I couldn't talk to anything over it. The output from irdadump seems to
indicate something is not right -- with SIR I get a flurry of messages
every five seconds, not just one.
