OK, there are a few new changes that we are making, and I'm working on updating the scripts again. For NAND, we are now compressing the modules into a Squash file system and putting that under /system/lib/modules/'uname'.sqsh. For this, we need to install squashfs-tools and make a few minor adjustments to the script
Edit: And apparently we have to use a specific version of squashfs-tools, so v4 that installs through apt-get install squashfs-tools will not work. I'll have more details later.
