TOM! That's super the cs553x_nand.c was what I was looking for. We have a
NAND directly conencted to the IDE bus. Currently the BIOS is setup for IDE
so we have to play with the muxing somewhere as you suggest.

SST49LF016 is the FWH, I would bet you are using an SST49LF004 now.
They are non-stocked, but available, at mouser:

Maybe you aren't looking for the right thing. Some pins on 553x are muxed
between the IDE controller and the NAND controller. If you mean that you
want to use the 5536 internal NAND controller, the driver is:
(make sure the muxing is set correctly by your firmware)
If you have some sort of IDE-NAND bridge device (like those in CF cards),
then you just use the IDE driver.
