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?
