 Those changes appear to be make it so that disklabels can use the first
 2 TB of a disk. I can verify that problem is fixed, but that's not the
 main problem of this ticket. I'm not trying to use disklabels (or CCD,
 VND or RAIDframe).
 The main problem is also fixed in -7 and -current.
 It looks like a lot has changed in dksubr.c.
 You can close the ticket anyway as I only need this in one place for now
 and I can use a -7 kernel there.
