OK, there's merit in this approach: it certainly moves the argument
about how to encode the signature out of my backyard :)

Should we just bite the bullet and create a new syscall:

SYSCALL_DEFINE5(init_module2, void __user *, umod,
		unsigned long, len, const char __user *, uargs,
                unsigned int, siglen, const char __user *, sig)

But I'm easily swayed if you prefer the current approach.

Thanks,
Rusty.
