I was experimenting with this too.
I made two ports of other fdisk utilites that could handle extended partitions:
OpenBSD fdisk and Linux fdisk.
If you want them, go:
Note that Linux cfdisk is included in the linux fdisk package but doesn't work.
The port is just enough to be able to edit ptable with linux fdisk.
OpenBSD fdisk seems to work fine.
Hope this helps!
