Nope, it broke because BenH added code to have either the PMU driver or
the atyfb driver register a backlight control callback (depending on where
the power control logic actually resides).

Compile you own kernel, and add a || machine_is_compatible("PowerBook1,1")
right after the || machine_is_compatible("AAPL,PowerBook1999") in
arch/ppc/kernel/pmac_support.c:register_backlight_controller(). That fixed
it for me. I'll resync and see what BenH did there later today.
