Because chosing the correct firmware requires making a runtime policy
decision, the firmware is of variable size (anywhere from 12MB to 16MB)
and it needs to be reencoded with something resembling PPP framing
before it gets dumped to the device. It's certainly possible to do it
in-kernel, but it'd be rather a lot more code and allocating that much
unswappable space sounds like something that would make some usecases
impossible.
