Wow... that's really flattering to see some of my commits copied to another kernel! That made my day.
I do wish he'd have taken the time to drop a message to me... just a "fyi" type thing, but that's not a big deal.
I've done recovery blind for other devices, but I can screw up all kinds of things and recovery will still work.
However, normal boot kernels are an entirely different can of worms, and there are a LOT of things that might break on these tablets. In addition, I don't have any of the 3g models, so I would have no possible way to diagnose if things went wrong with the modem. Others might be willing to tinker there. I'm not.
