Yeap. That's how I was saving the options..

Well, what tree are you using? The only iBook2 specific parts right now are
to check for PowerBook4,1 before PowerBook2,2 (since this one should be able
to have the powersave nap stuff going..). pmud is finding the device I
believe, it's just that it's writing settings to it just before the kernel
gets a chance to reprobe and so when that happens, it's reset again..
