It should not be too hard.  The extra members are only used in
specific parts of the code, mainly in the i386/pc directories.
Perhaps I could add a member which points to a user defined data
structure.  In that datastructure the extra information can be stored.

The BSD disklabel is a weird special case.  Perhaps we need some kind
of nested partitions or so.  I don't know if that will make sense
because I have no knowledge about BSD slices and how they are used.
