On Linux there is a tool called `hdparm` that gives this sort of
information.  Does this exist on NetBSD?  If not, what would its
equivalent be?

In a pinch I use `fdisk` to get this information on Linux.  But I'm not
sure whether the information it yields is canonical truth.  I'm starting
to use `cfdisk` and `parted` more often on Linux -- precisely because
`parted` helps with exactly this very issue of alignment.
