Hei hei,

This does not revert cleanly.

I tried this in atmel_nand_init():

+       /*
        if (nc->mck && nc->caps->ops->setup_data_interface)
                chip->setup_data_interface = atmel_nand_setup_data_interface;
+       */

So this basically skips all those timing init, right? If I do this I get 
the timings which were applied in U-Boot and the NAND-Flash just works.
