Yes, the problem is that you are missing mask_gpu_interrupt0=0x400 in your
/boot/config.txt as explained in [0]. That's why patch 2/5 added a config
option for this. Add the following to your conf/local.conf and should work:

MASK_GPU_INTERRUPT = "0x400"

I also needed to add DISABLE_OVERSCAN = "1"
