reading ancient floppy formats

I want to rescue the contents of some old floppy disks. They are 5.25
inch quad-density with a 7th edition UNIX filesystem on them.
The normal way to select the appropriate floppy drive configuration is
to select the right device node. The closest is /dev/fdnh720, but that
isn't quite right (I need 10 sectors per track). So I think that I
need the setfdprm command.
Unfortunately, the setfdprm command was dropped from Fedora around
Fedora Core 6. Here's the changelog entry from util-linux
* Tue Aug 16 2005 Karel Zak <kzak at redhat.com> 2.13-0.2.pre2
...
- removed: elvtune, rescuept and setfdprm
Does anyone know why this command was removed? Perhaps the device
driver no longer had the necessary functionality.
Is there a newer better way to read my disks?
Gene: this might be a question for you. I see you posted something to
the kernel list about setfdprm a couple of years ago.
