well. at the risk of double posting. some. Choff has been kind enough to provide more intramfs information which was a required piece of the puzzle, one person has successfully duplicated his work (I believe and is running other tests) on a 4NT.
You appear to have a 4? err. then just go do it yourself. the two main threads about it are on here somewhere. heck might even be this one.
you also have a 3. I would like to do a 3 also as a mouse (well, "something HID") coupled with the keyboard / ext keyboard would be dreamy. Sound support seems a given really with the right bit of kit as soundcard manufacturers generally fall over themselves to ensure compatibility in most things. on a 3 seems unlikely now.
corner case trackball drivers or obscure webcams? YMMV... wildly
Honestly this really is more a case of looking at one block of code and splatting the changes into another. not a really very high brow programming job. more like something someone with some docs, a device, a cable, and a braincell could probably figure out given enough time and patience.
Seriously, you can do this. (I don't have a 4 btw)
