With the patch I committed, the spurious fd4 device should not be
showing up (see your devinfo above). I looked more closely at your ASL
and it indicates that the floppy drive device depends on the dock. It
appears if the dock is not present at boot, the _STA method of DOCK
disables the floppy drive (DKFS -> 0). Can you tell me more about the
status of your docking station?
