Attic - there may not be. This appears to be yet another one of the fun "features" of this phone where you need to poke registers to turn things on and off (e.g. the GPS LNA) and fortunately there was a reference to that in the source for the kernel that I was able to find. I have ZERO belief that such a reference will be found for the Wifi side of things, as that's all in the libra.ko loadable and we have NO source for it. I also have good reason to believe the same issue exists in the wifi module as other libra.ko files, which should work (same hardware) don't, and some throw errors strongly implying that the power is off to parts of the wifi chipset. There's certain things that are kinda hard without source but you can find pieces of what you need and then there are things that are just a real BITCH. The Wifi driver is a major problem and among other things is likely to preclude the hotspot working too.
