I did some research some time back on why there are no linux drivers for the broadcom chips.
The rumors that are going around is that the broadcom chips can change and pick up many different frequencies and are greatly flexible. I hear people are afraid that this will be misused by linux people because we have the intelligence to do so. They are afraid of people getting into government frequencies and what not. How much is true I don't know. I really don't know what to believe, but I'm not ruling it out. It may very well be possible. From what I read, these chips are somewhat complicated. I personally would really like to know the truth, because I cant say I wouldn't misuse that kind of power
, but like I said, they are just rumors. I have nothing to say that it is fact.
