Please note that the bug I found in the nsc-ircc driver also
seems to afflict findchip, such that findchip incorrectly
reports the PC87338 to be in legacy mode when it is, in fact,
in PnP mode. If your chip is in PnP mode and if findchip
thinks it's in legacy mode (do "findchip -dv" to find out)
then the information it is reporting is incorrect because
it is read from the legacy mode registers rather than from
the PnP mode registers. That may explain why the IRQ reported
above is 9 rather than 4. I'll let the IrDA guys fix the bug in
findchip; I haven't looked at the source, but I'll bet there's
a ">> 4" where there should be a ">> 3". :)

This looks okay. I think that before you proceed any further
you should apply the patch submitted in my
"[Linux-IrDA]Re : [PATCH] nsc-ircc" e-message and try again.
I'd like to take this opportunity to thank the Linux IrDA team
for its hard work.
Cheers.
Thomas
