However, most developers on PPC4xx are interested in eventual deployment. Kernel math emulation is slow relative to a soft float enabled userland so using something like ELDK or MVL with PPC4xx/8xx makes a lot more sense. If you want to leverage binaries from Yellowdog/Debian/foo that are compiled for a classic PPC processor rather than natively then you'll need to enable math emulation.
