I am still hoping that we will get to the point of being able to build
a single binary kernel for both iSeries and the rest (pSeries, pmac,
etc.).  If we put in this patch then we'll undoubtedly forget to take
it back out when we do get to the single binary kernel.

Does it cause any actual problem to have CONFIG_ALTIVEC offered on
legacy iSeries?

Its just an unneeded question when running oldconfig on an older .config
for iseries. I cant test if it causes any trouble.
CPU_FREQ is similar, but I dont see an easy way to hide it.
