The issue is that the control register is within the rest of the
register area (i.e., 0x3f0 is already mapped because it's part of the
0x3f0-0x3f5 region).

I can make only little sense of dev/isa/fdc_isa.c;  I have no idea how
that is supposed to work and whether we should expect the control
register to potentially be at that offset, or whether it is an error in
the ACPI table.

Can anyone read fdc_isa.c and fd.c without heavy medication?
