It's probably my debug stuff that is bogus. One of the string pointers
passed to printk %s seems bad, and instead of being a proper kernel
pointer it's "0xaf0f48ef7bdef7bd". So trying to access it causes a GP
fault (it's not a validly formed pointer)

I'm not seeing what the problem is, but I'll mull on it..
