Where's the problem? Use .../disc for whole disc or .../part4 for "normal" access. (Or /dev/hdc and /dev/hdc4 if you prefer) It is nice if partition code can detect it but it is not ide-floppy driver problem.

Why complicate things more than needed?

When I boot without media in Jaz drive I get something like "no media inserted, assuming 1GB 512B per sector". Actually I modeled my patch from this - use some default values reported by drive when no media currently exists.
