Export symbols help a lot, and it gives you a good idea of what is going on; with the exception of the decompiler giving goto statements that jump all over the place and make things confusing :/ But again, it's legacy. As for newer gens - I thought they are already provided by Broadcom devs in the kernel? I may be wrong, I can look later. Thanks :) -Josh
