Aah, I just realized what's wrong. Your u-boot must still have the
short kernel size setting. This prevents kernels build with
"moredrivers" from booting.

To fix this,
- bring up the boot menu of NAND u-boot
- switch the console to USB
- enter the u-boot command line with

  neocon /dev/ttyACM{0,1,2}

  (or use the serial communication program of your choice)

- enter the following two commands:

  setenv bootcmd setenv bootargs \${bootargs_base} \${mtdparts}\; nand read.e 0x32000000 kernel 0x300000\; bootm 0x32000000

- you can now boot with


The change is persistent, so you'll be able to boot large kernels
from now on. A small drawback of this change is that loading the
kernel now takes a little bit longer.

You don't need to install Qi for this.
