Are you living on a different space/time continuum ? :)

First, there is no such thing as a powerbook g5 yet ...

Then, if it's a g5 machine, no kernel supports suspend and cpufreq yet

Finally, the SMU support upstream is very basic, I rewrote the driver
but haven't merged the new one yet.

You need a biarch (32 & 64 bits) toolchain and make ARCH=ppc64

Yes, on some deskop G5s, but not on the iMac yet, it's a different chip.

None of that code in arch/ppc/* is suitable for ppc64 machines anyway,
you are mixing 32 and 64 bits kernel here. The cpufreq code isn't
working on any SMP machine at the moment anyways due to the way it
recalibrates the jiffies.

Altivec is supported on both 32 and 64 bits kernels.

This option is not supported on 32 bits kernel, it's a Kconfig mistake
that it lets you turn it on.

Just don't try to build 32 bits kernels for G5, this isn't supported
anymore and I will remove the option soon
