Mine is a bit older:
cpu : PPC970FX, altivec supported
clock : 900.000000MHz
platform : PowerMac
model : PowerMac9,1
I used to use powernowd (userspace daemon) on all my past builds,
but this time I gave it a try without. Now I'm just echoing
'ondemand' to /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
and as the line above shows it idles at the slow speed. But it
ramps up to its full speed (1800 MHz) doing 'tar -xvf', only to fall
back. It also ramps up running configure scripts, unlike my x86
boxes. This is with a 3.10.12 kernel.
So no, I haven't seen the patch and I appear not to need it.
Unfortunately, even at full speed it still takes for ever to
compile things (just over 8 hours to build and install firefox-24).
