Looks OK, yes.

But I'd pass `val' directly, so the function can use extra fields in
values that inherit from registerv.  You could drop the `data' field as
well, at that point.

This just makes it more OO, and maybe experience would show that it
actually makes things worse (just adds unused extra flexibility), so
I'll let you judge.  Either way is OK with me.
