I think he meant packaged with the kernel and not built statically into the
kernel binary; although if the firmware is sufficiently separate and the
build process just links it in I don't see why that would be a problem
either, sort of like how nVidia does their driver. Even barring that, you
could easily throw it in an initrd or initramfs image to make it available
for early initialization.
