That's not your problem.

My suggestion is to use the automounter to access the disk... in newer 
NetBSD (might be 1.4 and later) there is an example file for cdroms, which
can be adapted. But see below.

Yes. See below.

Thats just a warning. It should work anyway.

Does bbogart have permissions for /mount/zip?

Uhm, I don't know what the history of msdosfs support in NetBSD is. Ask on
tech-kern about that.

"unused" == "there is no typed disklabel entry".

The default fake disklabel that is generated when no disklabel can
be generated from on-disk information (on NetBSD/Amiga from the
RDB) contains one partition "c" that covers all the disk.
