Thanks. I managed to do it with Linux parted. Gparted doesn't accept
sectors, only cylinders or {M,G}bytes. Back into Debian. Now, with
regards to installing OpenBSD:

And that's where the problems started in the first place.

At the prompt:
(W) (G) (E)

I choose (E) edit. Then, recalling from memory, I selected (disk) and
changed the NetBSD filesystem to OpenBSD. After that, I couldn't go
anywhere else. I didn't know what to do and I must have selected the
whole disk. I wanted to mount / on the ex-NetBSD partition, and that's
where I got stuck.
