This patch saves 28K on my s2895, and 55K on qemu.  Anybody have a
strong objection to that?  Are we trying to have bootblock size be
constant for each board?  Does it mess up future plans for backwards
compatibility?

It uses an alignment of 256 bytes.  Is that sufficient?  Is it necessary?

Thanks,
Myles
