No one has done any enhancements for dd since the last time you asked.

But you can make this happen yourself, by using the DJGPP File-System
Extensions.  Write an extension that recognizes /dev/fd and redirects
all I/O for such files to BIOS functions.  I once wrote such a module,
and even made a version of dd that could read floppies on the sector
level.
