The updated ones don't anymore.  They just align to 1MiB + whatever
the drive requests for offset (the offset-by-one thing).  They will
basically behave the same as windows vista/7 ones, so it's already
fixed.  What we can argue is whether adding CHS tricks on top to make
those larger alignments somewhat meaningful w/ CHS interpretation too,
which I'm objecting on the ground that it doesn't help compatibility
at all.

Thanks.
