What did you find exactly? Maybe we could get a link to your findings, or the basis for them?
I hope you're referring to building a 2nd init recovery. Otherwise, good luck with that. The kernal source is nowhere to be found. I've "bricked" 3 Fierce's messing with stuff I wouldn't even consider system vital. Hijacking that init and running a "VM" on top of the already running Android instance is our safest bet. There's a guy that goes by HashCode i believe, you might want to try and get a hold of him about getting "SafeStrap" on our device. Essentially, from what I gather, it's like having Grub Bootloader where you can boot to any partition/ROM slot available. "Safest" does not mean safe though. If you need help writing or testing any scripts.sh to run on boot, let me know!
If you are referring to mtkDroid/spFlash tools

Here's a little bit on running boot scripts.
