First, this is an x86 only issue; it is my doing to get more info for
sysinst.  I guess there is a glitch in scsi sd that causes it to call
disklabel three times (per disk?).  I'll look for this unless someone
else gets to it first.

Someone else reported this, too.  What perplexes me the most is that
this reports a BIOS geometry of 256 heads.  I don't know of any scheme
that should report this:
	1.  Do you have only netbsd on this disk?
	2.  What does fdisk say.
	3.  How did you initialize this disk.
