Actually I think the opposite is true - The low level asm code is all
placed at the bottom (or is it top?) end of the Boot Flash rather than
interleaved in the rest of the .text section. This is critical for the
real mode code as there is a tight limit on the jump lengths. This patch
makes it all the more consistent
