Only thing you need to worry about is this:
"Affect on permanent Root:
If you currently depend on a custom kernel's initramfs to provide permanent root, then flashing this kernel will lose root for you, because I used the stock initramfs. You can always flash right back to the other kernel after you've played with this. If you rely on the original joeykrim "one click" method of permanent root, this kernel will not interfere with that. If there is interest, I can repackage this using an initramfs that provides permanent root."
And since I don't believe there is any non-root method to do this, I'm going to move this thread over to ROMs/Hacks.
