The list of included modules is different on cdrom d-i image, netboot d-i image, and hd-media d-i image. One way to check it out would be to unpack the d-i image initrd.gz and look what is in there. The "/proc/config.gz" would not help as it would provide info about what is compiled, but not what is included in d-i. The fact that floppy works in final installation likely means the module is in fact compiled but not included in d-i image. Therefore, the way to go would be to figure out which module is needed to provide access to floppy on your platform and then work with kernel team on inclusion of the module in in the d-i initrd.
