Be aware that fdisk will fake up a partition table if the volume has no
table. Look for a message like:

warning: invalid partition table found

If you see that then there is no FDISK partition table.

Try setting

sysctl kern.geom.debugflags=16

before running fdisk. This stops GEOM protecting the drive/partition  
and allows fdisk to open it. I think fdisk and bsdlabel have been  
taught about GEOM in 6-current, but I very might well be wrong.
