I suspect that none of the developers of the i386 PC support had
access to a machine that still used a 720K floppy drive.

After a very quick glance through the source code, it looks like
most/all of the relevant code lives in the hal_cpu_init macro in
hal/i386/pc/<version>/include/platform.inc. To add support for 720K
floppies you would want to add a configuration option, and then modify
this initialization macro to cope with different types of floppy
drive.
