Bug Description
Binary package hint: kernel-
CPU scaling on G4 Tibook does not occur with current hardy kernel. The cpu_freq modules must be compiled in the kernel to work.
All other previous versions of Ubuntu worked fine.
These lines must be all changed to built-in (y) for power management to work.

I tested a vanilla 2.6.24.2 kernel configured with a pmac32_defconfig under hardy (uses built in cpu_freq), and scaling works properly.

Bug remains in 2.6.24-8-powerpc
Please may we have freq scaling back without having to build our own kernels.
