Yes - I see now from the archives that there was disagreement as to how 
to obtain the CPU frequency to pass to OpenBIOS, and while the 
FW_CFG_PPC_CPUFREQ value was removed from the final QEMU commit, it 
still remains in the related OpenBIOS commit.

Well at least it explains why when booting an PPC OS in QEMU/OpenBIOS 
all the CPU speeds appear as 0MHz ;)
