Understood, but I've incorrected filled the previous bug against
linux-3.0 when i meant linux-3.1

I wasn't suggesting making the drivers built-in to fix the problem, I
was just trying to note that building the custom kernel with those
params made the trackpad work with multitouch capabilities.
If I blacklist that module, should bcm5974 be loaded at start?
