Should the kernel be able to execute AltiVec code?  Or should it be
treated like the FPU?

I dimly remember running into the same problem years ago when gcc3 ( or was it 4 ? ) started to emit altivec instructions if the CPU flags allowed it to. The solution was to build all kernels with -mno- altivec when using -mcpu=74xx. IIRC the consensus back then was to treat altivec like the FPU and don't use it in the kernel.

have fun
