I don't know what is going wrong here. I often use this driver with
files > 3.5Mb, works for me. Can you add a #define DEBUG in
drivers/nand/nand.c and see if it's always the same location that fails?
You could also make your kernel partition a bit bigger so that the
rootfs starts at another place and see if it's still the same location
that fails.
Have you tried lowering the Nand clock?
