Yes, I do have a valid partition table.  It is exactly byte-by-byte
identical to the one I get after I zero sector two and re-run fdisk.
The fact that there is unwanted data in sector 2 does *not* make it any
less valid.

What's more, this could have easily been avoided if geom_whatever gave
the partition table precedence over the label it found in sector 2.
