I think we should align, by default, much more aggressively than that --
because frequently we just don't know what the real physical alignment
is (think of flash media, which uses large erase blocks underneath.)
Windows aligns partitions 1 MB boundaries by default now -- I think
that's probably a reasonably good idea, at least for any disk that's not
tiny, say 256 MB or less.
