The 16 MB limit is more about preserving 24-bit addressable memory than about safety: it is a useful resource to certain physical devices and we do not want to reduce that resource by ~12.5% by putting a ~2MB kernel image into it.
But yes, we want to load above 16 MB, if RAM size makes it possible.
Thanks,
