>Description:
        
On booting, my system reports:

fdc0 at acpi0 (FDC, PNP0700)
fdc0: io 0x3f0-0x3f5,0x3f7 irq 6 drq 2
fdc0: expected BUFFER, got 4
fd0 at fdc0 drive 0: 1.44MB, 80 cyl, 2 head, 18 sec
fd1 at fdc0 drive 1: density unknown

The "fd1" is new (sometime since April 2008, not sure when).  "fd1" is disabled
in the BIOS, and not physically present.

This issues seems only cosmetic in nature.
