Thanks.
I'm looking at adding at least dvh for now.
However, I want to test it, too, of course.

And that's not as simple, due to differences in how the
existing dos-based test responds when I substitute dvh.
I'll post an updated patch later in the week.

I'd like to reuse the same exact testing code as used
for dos partition tables, but that may not be feasible.
