A small patch allows you to use NSC PC97338 SuperIO chips that do not respond on the standard configuration ports with FastIR irda drivers.
The patch adds an option to overwrite the default behaviour to probe for the chip but takes over whatever port address, IRQ, and DMA channel you have specified.
The ports to use can be setup in the BIOS. I have already contacted the maintainer of the driver, however he hasn't yet found the time to answer me.
