There are only two ways currently to find fd0 on ISA systems: ACPI _FDE 
probing and hints.  The acpi probe automatically falls back to the hints 
system if _FDE fails so you should leave the hint.fd.0 lines in but 
comment out hint.fdc lines (as you've done).

I think the problem is that ISA is creating a duplicate fdc0 device via 
the hints.  I'm not sure the best way to solve this.
