Yes.

This is stuff which is really old and crufty.  I would be happy to
return ENOTTY for this ioctl call.

No question.  Do you have any suggestion how?  I suppose one way would
be to ignore errors if you can't get the partition information
indicated by the last letter.  Another, tacky one would be to
recognize the path name (/dev/vinum) and go by that.  But that's even
worse than the -V flag.
