It seems that message is generated when geom_mbr isn't loaded.  I was
running fdisk against an md(4) disk and after loading geom_mbr I got a
new message saying it couldn't find geom "md0".  The new partition
table showed up when I ran fdisk again, but after detaching and
reattaching using mdconfig the changes hadn't been saved.
