This is likely unacceptible in the embedded market. We're using boards with a UP 486 133's on them (actually AMDs, but you get the idea). We need some way to build kernels for these boxes. It sure would be nice, but isn't required, to have the same kernel for pentium UP machines. I would have no problem saying SMP is only supported on Pentiums or newer.
