You should have set these config options anyway if you're compiling for a
TiBook... The backlight control is the one that switches on
CONFIG_PMAC_PBOOK IIRC.

m3mirror does not poke the r128 registers itself but asks the kernel to do
so. You can try to write a version of m3mirror that does the register
tweaking itself (minus supervisor mode instructions) by taking the
appropriate code from the kernel sources. At least it worked for the
mach64 M1...
