Well, I've tried passing all sort of different parameters to the
module but it comes back with errors:
=======================
# modprobe -v smsc-ircc2 ircc_fir=0x100 ircc_sir=0x3e8 ircc_dma=1 ircc_irq=3
insmod /lib/modules/2.6.15-gentoo-r1/kernel/drivers/net/irda/smsc-ircc2.ko
ircc_fir=0x100 ircc_sir=0x3e8 ircc_dma=1 ircc_irq=3
FATAL: Error inserting smsc_ircc2
(/lib/modules/2.6.15-gentoo-r1/kernel/drivers/net/irda/smsc-ircc2.ko):
No such device
=======================

I can't see any IRQ conflicts with the IrDA though:

I even excluded irq 3 in /etc/pcmcia/config.opts, but it made no
difference.  I don't know what else to try.
