/me throws the towel.

I know next to nothing about floppy.  It's just that all parties ...

  (1) hw/block/fdc.c
  (2) hw/i386/acpi-dsdt-isa.dsl
  (3) hw/isa/lpc_ich9.c

... should agree on what the floppy io ranges are.  Right now they
don't, for whatever reasons.  And I simply don't know what are the
correct ranges.  So I leave fixing this up to whomever knows better this
than me.
